Claims

[Scope of utility model registration request]

In a magnetic disk degaussing device for loading a magnetic disk jacket containing a magnetic disk and erasing information recorded on the magnetic disk, when the magnetic disk jacket is loaded into the degaussing device, the magnetic disk jacket is removed. A lock engaging part for holding the opening/closing lid of the degaussing device in the closed position on the reference pin for positioning, and a mounting prevention device for making it impossible to mount the magnetic disk jacket with the erasure prevention claw removed. 1. A demagnetizing device for a magnetic disk, comprising: a demagnetizing device for a magnetic disk;
