Digital linear Tape was derived form TK-70 & TK-50 half inch cartridges that were developed by Digital Equipment Corporation (DEC). Afterwards Quantum took over the development & production of DEC tape in the year 1994. The TZ-30/TZ-50 had capacity of 100MB which now has been increased to 800GB in the DLT-S4 tape format. The target of the Super DLT tape format was the storage market of high-end server. The most powerful and high speed addition in the range of DLT tape technology is the DLT-S4 with 1.6 TB compressed capacity. Recording mechanism of the DLT is serpentine linear. The other formats as AIT and DAT utilize the helical scan mechanism. The size of the DLT cartridge is four square inches and the media is of half inches. Recording space is enhanced in the DLT-S4 which provides space to store 800GB data.
Super DLT technology is the extension and advancement of the DLT tape format. DLT technology is the major backup tape format that is offering reliable and superior backup solutions to the companies with low overall cost. The SDLT tape drives are based on the mechanism of magnetic storage LGMR. Reliable and powerful optical & magnetic technologies are combined in the LGMR mechanism that dramatically increases the security registrations of media data surface’s sustainability.
SDLT is the major and superior tape format of the digital linear tape technology. Core of the LGMR mechanism is servo system POS. Servo laser and optical magnetic frown the data is combined with the POS for cycling. The sensitivity of pivoting optical is very lower to any influences from external. POS helps to reduce the production cost. In the presence of POS, there remains no need for band’s pre-formatting. Implementing the optical servo at the media’s back that is unused, increases the space to store the data. So the actual data has all the entire available application’s storage surface. Optical laser moves along media’s back while POS spins on single point.
For the ministry and backup medium of data center, Quantum SDLT is the best reliable and low cost technology which performance the backup operations efficiently. First generation Quantum SDLT has capacity of 160GB and the data transfer speed is 16 MB/s (native) and its next version SDLT-II tape format’s native space is 300GB and the compressed space is twice (600GB). Cost per GB of both these Quantum SDLT data tapes is very low and the output and performance is outstanding. So the companies can make investment in SDLT technology without any hesitation. Quantum SDLT-2 tape technology has transfer speed of 32 MB/second and it can read data from the DLT tape cartridges.
Its technology is blend of reliable, best and robust technologies of magnetic & optical with enhancements in the storage space and output. Super PET film is used in the SDLT-II tape cartridges to reduce the thickness of the tape by 10 percent. So that is why the storage space of the Quantum SDLT-II tape cartridge is more than the SDLT-I tape cartridge. The information system of optical leader is encoded on media’s back that increases the quantity of tracks at the media surface’s start. So, higher space is made available for recording of information in the Quantum SDLT-2 data tape cartridge.
