[57] ABSTRACT
A tray for supporting a recording disk in a disk cassette has a pair of diametrically opposed pivoted levers with operative ends which engage opposite sides of the disk to hold it in the tray. The other end of each lever covers a pin insertion hole in the disk. When respective pins of a playback device are inserted through the insertion holes, the pins push against the levers and cause them to release the disk.
