Abstract
According to embodiments, a magnetic disk apparatus includes a magnetic disk, a magnetic head, a temperature sensor, and a controller. The magnetic disk has formed therein a servo sector in which servo data including a first post code and a second post code is recorded. In the positioning of the magnetic head, the controller performs a correction using a third post code that is based on the first and second post codes and a first temperature detected by the temperature sensor.

A magnetic disk apparatus comprising:
- a magnetic disk in which is formed a servo sector in which servo data including a first post code and a second post code is recorded;
- a magnetic head;
- a temperature sensor;
- and
- a controller that performs, in positioning of the magnetic head, a correction by using a third post code that is based on the first post code, the second post code, and a first temperature detected by the temperature sensor.
A method for positioning within a magnetic disk apparatus, the method comprising:
- positioning a magnetic head on a magnetic disk in which is formed a servo sector in which servo data including a first post code and a second post code is recorded, wherein
- the positioning includes performing a correction by using a third post code that is based on the first post code, the second post code, and a first temperature detected by a temperature sensor.
