Abstract
A double side type flexible magnetic disc drive apparatus comprises a damper which imparts a damping force being proportional to the shifting speed and is held between a head shifting mechanism and a stationary part whereby damage of a flexible magnetic recording medium caused by shifting the heads can be decreased to prolong the life of the recording medium and the time required for reaching stable contacting of the heads with the recording medium can be shortened.
