Tape edge Servo band Even # wrap... -
Page 46: Recording Method
Viper 200 LTO Product Manual A track group is a set of tracks that is recorded concurrently. The sets of 12 data tracks in a data band are data sub bands. There are 8 data sub bands per data band. The data tracks are accessed in a serpentine manner. A wrap is a track group recorded in the physical forward or physical reverse direction. -
Page 47: Servo-Tracking Faults
Theory of operations C1 ECC As data is written to memory from the Data Processing unit, the DMA / ECC interface generates C1 ECC bytes and writes them to memory. As data is written to tape, the C1 ECC is checked, and an interrupt generated if there is an error. - Page 48 Viper 200 LTO Product Manual level data exhibits patterns of various sizes that repeat with varying degrees of regularity. Storage efficiency is increased if the redundancies or repetitions in the data are removed before the data is recorded to tape. Data compression technology functions to significantly reduce or eliminate the redundancies in data before recording the information to tape.
-
Page 49: Intelligent Data Compression
Theory of operations Intelligent data compression The tape’s compressed capacity is maximized through the use of intelligent data compression. The intelligent data compression hardware determines the compressibility of each record. If the size of the record is larger after a compression attempt than the native (uncompressed) size, then the record is written in its native form. -

Viper 200 LTO Product Manual Ultrium tape format This chapter summarizes the features and benefits of the LTO tape formats, and of the Ultrium tape cartridges. Overview of LTO tape formats Ultrium is one of two LTO tape formats. Like DLT tapes, LTO tapes are recorded using a linear serpentine recording technique. -
Page 55: Figure 19. Lto Cartridge With Door Open To Show Leader Pin
Ultrium tape format Despite its ultra-high capacity, the Ultrium cartridge is thinner than other existing single-reel cartridges. It measures about 4 inches square and is a little more than 3/4 of an inch thick. The data on the tape can be protected by a manual switch on the front of the cartridge, as well as by the cartridge memory (see below). -
