[edit] Servo
- "SDLT adds an optical servo system that reads servo patterns on the back of the tape."
I wish the article explained the significance of this sentence. The link to the servo article is useless in this context. — Johantheghost 14:19, 28 December 2005 (UTC)
Servo tracks are written on the back of tapes to keep the read/write heads on the correct data track. Newer tape media have very thin dense data tracks. 256, 384 and 768 data tracks on a half inch wide tape are now common. While moving from one reel to another when loaded in the tape drive, there may be some lateral tape movement that could cause the drive to 'lose track' of which data track it is reading. By putting servo tracks on the back side of the media, where it will not affect the actual data being stored, the servo system of a tape drive can tell precisely which track is being accessed and allows the tape drive to accurately position the tape media.

[edit] MB ?
What does MB stand for (in this article table)? mega bytes, mega bits? What kind of mega? 1000x1000 1000x1024 or 1024x1024?
Thanks?
[edit] Standard, de facto or otherwise
DLT is a technology, not a standard (except in the sense that many people use DLT for backups). The specification is tightly controlled by Quantum and anyone who wants to make a DLT product can only do so with Quantum's approval. -- Austin Murphy 15:04, 23 October 2006 (UTC)
