Sony Ait-5 & Ait-4 Tape Technology

The revolutions per minute (rpm) of the Sony AIT-4 data tape format’s helical scan head is 4,800. Information of higher density is recorded at an angle that is relative to edge of the AIT data tape reel. Loop of the AIT-4 backup tape drive is closed and the tape path is adjusted by the “self adjusting” mechanism that helps in accurate and highly precise tracking of the data tape. New and unique system of ATF (auto-tracking following) has been added to the AIT-4 tape drive which improves the tape drive’s effectiveness. For tape flutter, the servo adjusts itself and therefore it enables the space between the tracks to be much nearer when recording the data onto the tape reel.

The tape head (MIG metal in gap) of the Sony AIT4 tape drive is redesigned and enhanced. The average life of the AIT tape head is about 50,000 hours. AIT4 tape drive has mechanism for controlling the tape tension. It controls the tension of tape reel at one half. The other mechanisms of helical scan and the innovative tape head geometry help to further reduce the pressure between the tape media and head. The servo mechanism controls and monitors the fluctuations in the tape tension and helps in reduction of wear & tear of both the tape head and tape reel.

Sony AIT5 backup tape format is now even more robust and reliable as it has the new AME-III technology. The AME-III feature (Advanced Metal Evaporated) has incredibly enhanced the data storage ability and the data density. The other data tape formats paint the magnetic particle merely so this makes 50 percent of the magnetic material active. In AME technology, cobalt is used which is then vaporized and is applied directly on to the AIT tape reel. So the AME technology results in almost 100 percent pure magnetic material in the AIT data tape format. AIT tape cartridges suffer less from loss of data because of the AME technology as they loose less magnetic particles. It is because of the AME technology that the Sony AIT5 data tape media has remarkable 400,000 hours of life at duty cycle of 100%. Sony AIT-5 has ability of end-to-end passes of 30,000.

Sony AIT5 backup tape technology offers numerous advantageous and reliable features one of which the most important feature is the WORM (write once read many) technology. Backed up information on the tape cartridge cannot be wiped out or changed but access to the data is possible with the WORM technology in the AIT 5 tape format. WORM is very cost effective and beneficial for the storage of archive regulated and sensitive data. Sony AIT5 tape format provides all the advantages of WORM media technology. All the generations of AIT (advanced intelligent tape) format including the fifth generation AIT5 tape format has memory chip (MIC) in the AIT data tape cartridges. Memory in cassette (MIC) is non-volatile chip. MIC is built in the AIT tape cartridge. MIC enables the AIT tape media in fast searching of data and quick loading of tape media.

AIT tape media does not keep on tape index it rather maintains the information of system log, tape status, file index, backup information, user definable information and cartridge history. AIT-5 tape format takes further this innovative and groundbreaking technology of MIC. Sony AIT-5 tape media uses the remote R-MIC chip which is the advanced form of the MIC chip. In this AIT backup tape format, there is no need of connector and the memory chip communicates with the AIT tape drive remotely.

Tandberg Slr Data Tape

The base of the SLR tape format is the “linear technology” which is also base of the other tape formats including the Linear Tape Open (LTO), Digital linear Tape (DLT) and the Travan tapes. In the linear technology the writing of the data on the tape reel is done longitudinally, and then the tape head moves to next track after the tape end reaches. In this way the direction of the tape is reversed. So, in SLR tape the path for the data attains the shape of “S”. It is also called as “serpentine path”.

The linear tape format of the SLR backup data tape reduces the wear of the “internal drive elements” and that of the tape reel as well. Therefore, the backup rate enhances in the SLR tape format. The throughput is enhanced in the SLR tape format because it has the 8 MB data buffers. The data buffer stores the compressed data by using the inline compression. The tape speed of SLR is optimized by the “Auto sense”, which also helps to avoid the stop & start operations that are unwanted. The main features of the SLR backup data tapes are that they are low cost with efficient restore operations, high capacity and fast data transfer speed.

SLR is excellent, reliable and efficient data storage medium for longer period of time. The shelf life of SLR data tape is about 20 years. The SLR 7, SLR 60 & SLR100 tape versions offer scalable and storage capacity and data transfer speed. The SLR tape format is popular as high quality and high performer backup tape media. SLR technology protects and secures the valuable data.

Tandberg data provides the leading and successful backup storage solutions whose results are reliable with high level of performance. The SLR autoloader from Tandberg increases the efficiency of output as well as the protection of the tape solution. It has the reliable technology of SLR. The SLR autoloader from Tandberg can support 1 SLR tape drive and 8-cartridge magazine. The Tandberg SLR Autoloader lowers the intervention of the operator. It has the ability to back the system from one week to 2 months on its own without the intervention of the operator. Therefore, the Tandberg SLR Autoloader saves time and cost resources and provides timely, smooth and consistent backups. The interface of Tandberg autoloader is very user friendly. The cartridge magazine has Liquid Crystal Display.

The setup of Tandberg autoloader can be done very easily. The information about the loader mechanisms and activities of drive is provided by the display panel. Tandberg SLR autoloader also has powerful and reliable security features. The operator can protect the data by locking the loader using “security code”, so the magazine, cartridge and drive cannot be accessed.

The automated autoloader along with the “tape alert” provide the status and operations of SLR drive as well as all the media. The advantages of Tandberg SLR autoloader are that the control panel is very user friendly. It has been developed for the systems having 25GB to 800GB data. The storage management is easy because of the standard “barcode reader”.

Robust Slr Backup Tape Storage Media

The type and format of the backup storage medium used effects the future growth, investment protection and performance of the company. The restore & backup strategy are dependent on the format of the tape medium being used. According to the findings, more than five hundred thousand drives of SLR are installed in Servers of iSeries around the world. The SLR tape format is best suited for the “iSeries” and it protects the high volumes of data with fast recovery and backup performance. The SLR is the abbreviation of “Scalable Linear Recording” and Tandberg Data introduced the first generation SLR-1 tape in the year 1987.

Tandberg is one of the major manufacturer and supplier of the backup tape media products. The major tape formats of Tandberg are the Linear Tape Open (LTO), Digital Linear Tape (DLT) and the Scalable Linear Recording (SLR).

The product line of the Tandberg includes the backup tape libraries, tape autoloaders, media and backup data tape drives.

At first the SLR backup tape was based on the technology of QIC (Quarter Inch Cartridge). Afterwards the technology used was the SLR (Single Channel Linear Recording). Then new technology MLR (Multi Channel Linear Recording) was added and then to its present form of the SLR tape format. The SLR tape media products are highly scalable, reliable. They are also compatible both forward and backward with the other generations of SLR format.

In the SLR-7 tape the recording of the data is done on 2 tracks and is recording is done in parallel. While in SLR-60 & SLR-100, the recording is done on 4 tracks. The data is recorded on the media in such a form that in case of degrading of media, the data could be read in the operation of restoring. The attributes and technologies that enhance the speed of the SLR tape are the “auto sense function”, “inline compression”. The data buffers are also large in the SLR technology. The SLR-1 tape format gives the tape solution for entry level and at a low cost. Since the year of the introduction of SLR, about 2 million drives of SLR have been installed by the companies worldwide.

The cost of ownership for the SLR tape format is very low because it has low rate of failure which is about 1.5 percent. The SLR is best for those enterprises where the field maintenance is low.

The SLR-60 has 30 GB native capacity and 60GB of compressed recording capacity. The data transfer rate is 4MB/sec with 8MB/sec of compressed rate. The transfer rate per hour is 15GB/hour with compressed rate of 30GB/hour.

The SLR-100 has 50 GB native capacity and 100GB of compressed recording capacity. The data transfer rate is 5MB/sec with 10MB/sec of compressed rate. The transfer rate per hour is 18GB/hour with compressed rate of 36GB/hour.

The reliable and robust backup tape format choices for the small & medium business enterprises are the SLR-60, SLR-100 and the SLR-140 backup tapes.

The SLR technology has the capacity, technology and the features to fulfill the future’s data backup demands and requirements of the companies in efficient and cost effective manner. The roadmap of the SLR tape format has the ability to meet future demands for backup data storage. The roadmaps do tend to change with the passage of time and when the future generations come close to the existing and the present generations.
