| 摘要 |
The present invention relates to a storage device and a servo recovery method for the storage device, which restores the head to a track when the head goes off from the track of a storage medium, and whereby it prevents the servo recovery process from being continuously called over a short period of time. The storage device comprises a storage medium, a head and a control circuit which performs the servo recovery process. The servo recovery process, having multiple recovery processes, is called up when off track is detected. The frequency that the recovery process is called up is detected, and one of the multiple recovery processes is executed according to the detected call-up frequency. A different recovery process is performed when the call-up frequency is high, therefore this recovery process makes it possible to prevent frequent occurrence of the off-track state.</PTEXT>
