Rate-13/15 maximum transition run code encoding and decoding method and apparatus |
摘要 |
Provided are a rate 13/15 MTR code encoding/decoding method and apparatus. The encoding method includes: generating a predetermined rate-13/15 MTR code in which 13-bit data corresponds to 15-bit data; outputting input 13-bit data as a 15-bit codeword according to the rate-13/15 MTR code; checking whether codewords satisfy a predetermined constraint condition by connecting the 15-bit codeword and a subsequent 15-bit codeword; and converting specific bits of the codewords if the codewords violate the constraint condition and not converting the codewords if the codewords do not violate the constraint condition. The rate-13/15 MTR (j=2, k=8) code includes: 8192 codewords obtained to prevent the number of consecutive transitions from becoming 3 at code boundaries in a modulation coding process. Data can be reliably reproduced with high write density, and a large amount of data can be stored in and reproduced from a magnetic recording information storage medium.
