Claims

[Scope of utility model registration request]

A magnetic disk recording/reproducing device main body, a magnetic disk jacket detachably loaded into the main body, and recorded tracks attached to the case of the magnetic disk jacket so as to count and display the number of recorded tracks on the magnetic disk. a counter; a counter drive shaft having a distal end that can be held in a non-rotating state in a keyhole-shaped holding hole of the counter and rotationally driven in conjunction with the magnetic head feeding mechanism of the main body; a spring that applies a biasing force to the shaft to bias the shaft toward the counter; and an operating surface of the main body so that the biasing force by this spring is effectively applied during recording and is removed when the counter is not in use, such as during playback. 1. A magnetic disk recording/reproducing device comprising a counter operation button reciprocably mounted on the top.
