Abstract
Provided are a method, system, and computer program product in which data is encoded for a plurality of tracks of a tape of a tape drive, by using an error correction code (ECC) scheme that applies a single code with code word symbols that are at least 10 bits. The code word symbols are interleaved along and across parallel tracks of the tape in the tape drive.
Claims20
A method, comprising:
- encoding data, for a plurality of tracks of a tape of a tape drive, by using an error correction code (ECC) scheme that applies a single code with code word symbols that are at least 10 bits;
- and
- interleaving the code word symbols along and across parallel tracks of the tape in the tape drive.
A tape drive, comprising:
- a controller;
- and
- a tape head coupled to the controller, wherein the controller is configured to perform operations, the operations comprising:
- encoding data, for a plurality of tracks of a tape of a tape drive, by using an error correction code (ECC) scheme that applies a single code with code word symbols that are at least 10 bits;
- and
- interleaving the code word symbols along and across parallel tracks of the tape in the tape drive.
A computer program product, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform operations in a device, the operations comprising:
- encoding data, for a plurality of tracks of a tape of a tape drive, by using an error correction code (ECC) scheme that applies a single code with code word symbols that are at least 10 bits;
- and
- interleaving the code word symbols along and across parallel tracks of the tape in the tape drive.
