Optimum gap determined recording/reproducing apparatus and method

A recording/reproducing apparatus comprising:

• a spindle motor unit including a spindle on which a flexible recording disk is placed to be rotated so that information data are at least one of recorded onto and reproduced from the recording disk;
• a stabilizer plate disposed so as to face the recording disk;
• a torque detection unit configured to detect a drive torque applied to the spindle motor unit;
• an adjustment unit configured to adjust a gap between the recording disk and the stabilizer plate;
• and
• a determination unit configured to determine an optimum gap to be set to the gap based on the drive torque detected by the torque detection unit, the apparatus characterized in that
• the adjustment unit sets the optimum gap determined by the determination unit to the gap.
