    • Track Layout With the LTO-2 half-height drive, there are 512 data tracks on the LTO tape, numbered 0 through 511. Data track 511 is the track closest to the bottom edge of the tape (the reference edge). The area between adjacent servo bands is a data band. There are 4 data bands, each of which includes 128 data tracks.

  • Page 32 Theory Data Integrity Error-correction Code (ECC) The use of Cyclic Redundancy Checking (CRC), two-level orthogonal Error Correction Coding (ECC) provides a very low probability of encountering a hard error. During the read process, ECC correc- tion is performed on the fly without affecting tape streaming. There are two levels of Error Correction Coding (ECC).

  • Page 33: Data Compression

    Theory Data Compression Servo-tracking Faults During a write operation, if the servo system detects an error that may result in adjacent data tracks being over-written, the write operation is aborted. The write operation will not continue until the cor- rect servo tracking is re-established. Data Compression Typical data streams of text, graphics, software code, or other forms of data contain repeated infor- mation of some sort, whether it is at the text level where you can readily recognize regular repeti-...

  • Page 34: Intelligent Data Compression

    Software data compression should never be used because the LTO-2 half-height drive's built-in intelli- gent data compression is much more efficient than software data compression systems. The LTO-2 half-height drive uses a derivative of ALDC-2 lossless data compression that includes addi- tional control codes for intelligent data compression.

    There are many factors that can make backups appear to be “slow.” To achieve the highest possible transfer rate, the LTO-2 half-height tape drive MUST be attached to a Low Voltage Differential ( LVD ) SCSI controller capable of a minimum of 80 MB/s and MUST not share the same SCSI bus as another active SCSI device such as hard drives.
