Abstract

PURPOSE:To enable an uneven number track and an even number track to be precisely recognized and to prevent the occurrence of the run away of a device by disposing a pattern for an uneven number track for each uneven number track and a different pattern for an even number track for each even number track. CONSTITUTION:In a servo disk 10 of which a servo pattern is disposed every respective tracks for positioning a head, the pattern (e) for the uneven number track is disposed to each uneven number track besides the servo pattern and simultaneously to that, the different pattern (d) for the even number track is disposed to each even number track. Then an uneven number track signal or an even number track signal is generated by reading the pattern for the uneven or even number track with the aid of a servo head 11 and detecting the respective patterns (e) and (d) based on the read signal. Thus, the uneven number track and the even number track are precisely discriminated without being misrecognized and they are not misset at the time of initial setting when a power source is charged. As the result of that, the magnetic disk driving device with high reliability which does not give damage to the device due to the run away of the device and the like can be obtained.
