ABSTRACT:
In the read-write apparatus of the present invention, concentrated sliding of the read-write head in a specific area on the recording media is reduced. The recording media is rotationally set and the read-write head contacts the recording media to read and write information on the recording media. While the read-write head is accessing (read/write) the information on the recording media, a slide count calculation section calculates a slide count of the read-write head by monitoring the servo information of the recording media. The memory section stores the slide count calculated by the slide count calculation section by unit of access area. The relocation section suitably relocates the information recorded on the recording media in accordance with the slide count by unit of the access area.
