<p>A track access control system for a magnetic disc system including a magnetic disc (1a to 1d) having a plurality of servo tracks (SVT) in a plurality of track zones divided in a radial direction, a logical to physical track address translation unit, a track offset update unit, and a control unit, to access a magnetic head at a physical track with offset correction. The track offset update may be carried out in an initial condition, or when a seek command is received. Also, the track offset update may be compulsorily effected when the update is not effected in a predetermined time. In this case, the system may output a virtual error data.</p><p>In addition, the track offset update may be effected in response to a temperature change of the system. </p> |
