Abstract
According to one embodiment, a magnetic disk device includes a disk including a first servo sector including a first preamble, a first servo mark, a first gray code, and first burst data, a head including a write head which writes data to the disk and a read head which reads data from the disk, and a controller which stops write processing, based on a write mask gate different from a first servo gate executing read processing of the first servo sector and a write gate executing the write processing to the disk.
Claims20
A magnetic disk device, comprising:
- a disk including a first servo sector including a first preamble, a first servo mark, a first gray code, and first burst data;
- a head including a write head which writes data to the disk and a read head which reads data from the disk;
- and
- a controller which stops write processing, based on a write mask gate different from a first servo gate executing read processing of the first servo sector and a write gate executing the write processing to the disk.
A servo read processing method applied to a magnetic disk device comprising a disk including a first servo sector including a first preamble, a first servo mark, a first gray code, and first burst data, and a head including a write head which writes data to the disk and a read head which reads data from the disk,
- the method comprising:
- stopping write processing, based on a write mask gate different from a first servo gate executing read processing of the first servo sector and a write gate executing the write processing to the disk.
