Claims

[Scope of utility model registration request]

In order to sandwich and hold the single-sided recording magnetic disk together with the magnetic head of the magnetic disk device, a groove is provided in the pad facing the magnetic head from the outer periphery of the magnetic disk toward the inner periphery to form a concave pad; A magnetic disk characterized in that the groove width is tapered to become wider from the outer periphery to the inner periphery of the disk, and the magnetic head facing the tape is located approximately at the center of the groove width of the part. Suppressing mechanism.
