MAGNETIC DISK DEVICE AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18178128 titled 'MAGNETIC DISK DEVICE AND METHOD
Simplified Explanation
The abstract describes a patent application for a magnetic disk device that includes servo sectors with servo information for positioning control of the magnetic head. When read errors occur continuously for a specific servo sector, a correction value is used to adjust the positioning of the magnetic head.
- The magnetic disk device includes a magnetic disk, magnetic head, and controller.
- Servo sectors with servo information, including correction values, are written on the magnetic disk.
- The controller adjusts the positioning of the magnetic head based on the correction values when read errors occur.

Original Abstract Submitted
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.
