ク。 It consists of a disk-shaped core material made of a hard material and a thin magnetic recording medium in which a magnetic layer is formed on the surface of a flexible disk-shaped base material. In addition to joining the magnetic recording medium to the peripheral side, a cavity is formed between the magnetic recording medium and the core material by a recess formed on the disk surface of the core material, and an opening that communicates with the outside air is provided on the outer periphery of the cavity. Features a magnetic disk.
