DNA Evolution, the company's intelligent workflow solution built on Linear Tape
Open (LTO) and Linear Tape
File System (LTFS) technologies, allows media professionals to streamline their file-based workflows, work more efficiently, and save significant storage costs.
The new Tape File System Storage Manager offers data lifecycle management for multimedia systems, such as video and workflow files, when using IBM's LTO-5 tape libraries and its Linear Tape
File System (LTFS) Library Edition.
David Sallak: One of the advantages of Linear Tape
File System (LTFS) is that it is now being proposed into SNIA [Storage Networking Industry Association] as a standard within its specifications because data integrity across all devices in the future -- to be able to read the data -- is important.
The video heads travel diagonally across the tape at a shallow angle (see Figures 2 and 3), which is directly affected by the linear tape
URS stores images and information magnetically in RAID 5 towers with a nightly backup to digital linear tape
, which is stored offsite.
Storing up to 1.3 TB of compressed data (500 GB uncompressed) on a single half-inch tape cartridge, the high-capacity SAIT-1 drive combines the data density advantages of helical-scan recording with the longer and wider tape usually associated with linear tape
The two most widely supported of all these are the Digital Linear Tape
(DLT), pioneered by Quantum ATL, and Linear Tape
Open (LTO), spearheaded by Seagate Technology, IBM and Hewlett-Packard.
IBM Corp says it will be ready to introduce its first products based on Linear Tape
Open technology in the first quarter of next year.
Application of these criteria leads to the conclusion that digital linear tape
is the preferred storage medium to support the long-term storage of digital records.
Unlike a linear tape
system, the non-linear computer storage of video allows unrestricted search for plays in a memory data base.
Launched in the 70s by Sony, Betamax used a low linear tape
speed, narrow track pitch and large video drum to give high tape- to-head writing speed and more than three hours playing time from a small cassette.
