Abstract
An apparatus for recording and reproducing information stored on a photomagnetic disc, includes a magnetic head which produces magnetic field. The apparatus comprises a carriage radially movable with respect to the photomagnetic disc. A head supporting mechanism is shiftably disposed on the carriage between a loading position where the magnetic head is contacted with the end face of the photomagnetic disc to apply the magnetic field thereto and an unloading position where the magnetic head is disposed remote from the end face of the photomagnetic disc to be prevented from applying the magnetic field thereto. A locking mechanism is shiftable between a locking position where the locking mechanism engages the head supporting mechanism and a release position where the locking means disengages the head supporting mechanism. A driving mechanism is so constructed as to be energized during shifting movement of the locking mechanism between the locking position and the release position. A retaining mechanism for retaining the head supporting mechanism at the loading and unloading positions, respectively, is disposed on the carriage and the head supporting mechanism.
