Abstract
According to an embodiment, the magnetic disk device includes a disk medium and a control circuit. The disk medium includes a first region including a first track. The control circuit controls a write operation of first data to the first track, executes error correction coding of the first data during the write operation. The control circuit makes first determination on whether the written first data is protected by an error correction code. The control circuit sets a second track in a location adjacent to the first track in accordance with a result of the first determination.
Claims18
A magnetic disk device comprising:
- a disk medium comprising a first region including a first track;
- and
- a control circuit that
- controls a write operation of first data to the first track, executes error correction coding of the first data during the write operation,
