  • Page 45: Chapter 4 Theory

    This chapter describes operational theories used in the LTO-3 Tape Drive. The topics covered in this chapter are: • Track Layout • Recording Method • Data Buffer • Data Integrity • Data Compression Track Layout With the LTO-3 Tape Drive, there are 704 data tracks on the LTO tape, numbered 0 through 703.
  • Page 46: Figure 13 Layout Of The Tracks On Lto Ultrium Tapes

    Chapter 4 Theory Track Layout A track group is a set of tracks that is recorded concurrently. The sets of 11 data tracks in a data band are data sub bands. There are 16 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: Recording Method

    Recording Method The LTO-3 Tape Drive records data using write-equalized (0,13/11) Run Length Limited (RLL) code. RLL (0,13/11) Data bits are defined as follows: • • ZERO Data Buffer In its default configuration, the LTO-3 Tape Drive has a 128-Mbyte buffer. The buffer controller has a burst transfer rate of 320 Mbytes/sec, and utilizes bank switching to achieve a maximum average bandwidth of nearly 240 Mbytes/sec.
  • Page 48: Error-correction Code (ecc)

    Chapter 4 Theory Data Integrity The use of Cyclic Redundancy Checking (CRC), two-level orthogonal Error-correction Error Correction Coding (ECC) provides a very low probability of Code (ECC) encountering a hard error. During the read process, ECC correction is performed on the fly without affecting tape streaming. There are two levels of Error Correction Coding (ECC).
  • Page 49: Servo-tracking Faults

    Correction The correction depends on the number and types of errors involved: • • • During a write operation, if the servo system detects an error that may Servo-tracking result in adjacent data tracks being over-written, the write operation is Faults aborted.
  • Page 50: Data Compression Considerations

    Chapter 4 Theory Data Compression symbols point back to the original data string, using fewer characters to represent the strings. Because these smaller symbols are substituted for the longer strings of data, more data can be stored in the same physical space.
  • Page 51: Intelligent Data Compression

    The transfer rate depends on factors such as: • Compression ratio • Drive buffer size • Host computer input/output (I/O) speed • Effective disc speeds of the host computer • Record lengths that the host computer transmits Data compression algorithms can be tailored to provide maximum compression for specific types of data.
  • Page 52 Chapter 4 Theory Data Compression Software data compression should never be used because the LTO-3 Tape Drive's built-in intelligent data compression is much more efficient than software data compression systems. The LTO-3 Tape Drive uses a derivative of ALDC-2 lossless data compression that includes additional control codes for intelligent data compression.
