Abstract
A recording/reproducing apparatus including a disk cassette rotatably accommodating a disk-like recording medium and having positioning holes at least on its one side, a holder holding the disk cassette and vertically movable to cause the disk cassette to take selectively a first position in which the medium is attached to a rotational disk drive unit or a second position spaced above the first position, a shifting unit for shifting the holder between the first position and the second position, and a locking unit for engaging with the positioning holes in the disk cassette when said holder is in the first position for positioning the disk cassette, is disclosed. According to the invention, the apparatus further includes a locking unit provided for rotation along the thickness of the disk cassette. The locking unit is rotated approximately simultaneously with termination of insertion of the disk cassette into the holder for retaining the vicinity of the positioning holes of the disk cassette for locking the disk cassette relative to the holder.
