Claims

[Scope of utility model registration request]

A flexible disk processing control device consisting of a flexible disk processing control circuit and a storage device that records flexible disk processing control information, and a flexible disk that rotates the flexible disk near a magnetic head to write and read information. - In the disk device, a flexible disk processing control circuit obtains a flexible disk identifier from a storage device and sends it to the flexible disk device, and a track start position detection circuit for detecting a track start position of the flexible disk. , an identifier display that displays the identifier of the flexible disk that is required to be attached to the flexible disk device, and an identifier that turns the identifier display on and off based on the flexible disk identifier signal and the track start position detection signal. A flexible disk control mechanism characterized by being equipped with a display control circuit.
