  • Publication number: 20240096359
    Abstract: According to embodiments, a magnetic disk device includes a magnetic disk, a magnetic head, and a controller. In the magnetic disk, a plurality of servo sectors is arranged in a circumferential direction. Servo information including a post code indicating a repeatable runout (RRO) correction amount is written to each of the plurality of servo sectors. The magnetic head writes and reads data to and from the magnetic disk. In positioning control for the magnetic head, when a read error of a first post code continuously occurs, the controller uses a first RRO correction value, which is different from a second RRO correction value based on the RRO correction value indicated by the first post code. The first post code is a post code of a first servo sector, which is one of the plurality of servo sectors.
