摘要： A method for efficiently rewriting data to tape is disclosed herein. In one embodiment, such a method includes writing a data set to tape, the data set comprising S sub data sets of fixed size, each sub data set comprising N code word interleaves (CWIs). The method further includes reading the data set while writing it to the tape to identify faulty CWIs. While reading the data set, the method buffers the faulty CWIs (such as by storing, identifying, and/or marking the faulty CWIs) for later retrieval. When the end of the data set is reached, the method writes corrected versions of the faulty CWIs to the end of the data set. A corresponding apparatus is also disclosed and claimed herein.

摘要： A method for randomizing data to mitigate false VFO detection is described. In one embodiment, such a method includes simultaneously receiving multiple input data streams. Each input data stream is associated with a different track on a magnetic tape medium. The input data streams are simultaneously scrambled to produce multiple randomized data streams. The input data streams are scrambled such that different bit patterns are produced in the randomized data streams even where corresponding bit patterns in the input data streams are identical. The randomized data streams are simultaneously written to their associated data tracks on the magnetic tape medium.

摘要： Error correction coding is provided for codeword headers in a data tape format, such as a Linear Tape-Open, Generation 4 (LTO-4) data tape format. The data tape format defines a codeword quad as having first and second codeword headers interleaved with first and second codeword pairs, each codeword header comprising N bytes Ck=C0, C1, . . . , CN−2, CN−1 wherein K bytes C0-CK−1 of the first and second headers in a codeword quad differ such that if one is known the other can be inferred. Each header byte Ck of a codeword quad is redefined as comprising two interleaved (M/2)-bit nibbles, ek, ok. For each header, nibbles ek-eN−1 and nibbles ok-oN−1 are generated as a function of nibbles, e0-EK−1 and o0-oK−1, respectively. A codeword is assembled with the redefined headers the codeword quad is then recorded onto a recording medium.
