Abstract of the Disclosure The invention is concerned with a recording and/or reproducing apparatus for a flexible magnetic disk, wherein the apparatus includes a cassette holder in which there is inserted and held a disk casssette consisting of a cassette half rotatably accommodating a magnetic disk, a rotational driving device for rotationally driving the magnetic disk in the cassette half, elements for raising and lowering the cassette holder relative to the rotational driving device, and a head unit, which head unit has a pair of supporting arms movable between the inner and outer peripheries of the magnetic disk chucked to the rotational driving device and provided at their distal ends with magnetic heads and/or disk supporting pads slidably contacting the upper and lower sides of the magnetic disk, these supporting arms being arranged in opposition to the inserting direction of the disk cassette, with one of the supporting arms being turned in operative association with the up or down movement of the cassette holder so that the magnetic heads or disk supporting pads at the distal ends are brought into or out of contact with the magnetic disk. In this recording and/or reproducing apparatus, the elements, for raising and lowering the cassette holder are provided with portions operating so that the cassette holder in which the disk cassette is inserted is lowered with a delay at the side thereof towards the head -1- unit relative to the side thereof that the disk cassette is introduced, in order that, when the magnetic disk of the disk cassette is chucked in the rotational driving device the magnetic disk is clamped by the magnetic heads and/or disk supporting pads provided to the head unit after the chucking of the magnetic disk is terminated. -2-
