Abstract
According to one embodiment, a magnetic disk device includes a disk, a head configured to write data to and read data from the disk, and a controller configured to compress data transmitted with a specific size into compressed data, add data of a first pattern to the compressed data to generate first data having the specific size, execute an encoding process to the generated first data, output second data obtained by encoding the first data, and execute a decoding process to the second data input from outside based on the first pattern.
Claims20
A magnetic disk device comprising:
- a disk;
- a head configured to write data to and read data from the disk;
- and
- a controller configured to compress data transmitted with a specific size into compressed data, add data of a first pattern to the compressed data to generate first data having the specific size, execute an encoding process to the generated first data, output second data obtained by encoding the first data, and execute a decoding process to the second data input from outside based on the first pattern.
A controller comprising:
- a compressor configured to compress data transmitted with a specific size into compressed data, add data of a first pattern to the compressed data to generate first data having the specific size;
- an encoder configured to execute an encoding process to the generated first data and outputs second data obtained by encoding the first data;
- and
- a decoder configured to execute a decoding process to the second data input from outside based on the first pattern.
A decoding method applied to a magnetic disk device comprising a disk and a head which writes and reads data relative to the disk, the method comprising:
- compressing data transmitted with a specific size into compressed data;
- adding data of a first pattern to the compressed data to generate first data having the specific size;
- executing an encoding process to the generated first data;
- outputting second data obtained by encoding the first data;
- and
- executing a decoding process to the second data input from outside based on the first pattern.
