Claims

[Scope of utility model registration request]

A head drive mechanism that moves the magnetic head along the radial direction of the magnetic medium is provided on the base, and a spindle that passes through the base and drives the magnetic medium and is connected to the head drive mechanism to drive the head drive mechanism. 1. A magnetic recording and reproducing apparatus comprising: a motor connected to the spindle by a belt to rotate the spindle; and a speed detection mechanism mounted on the spindle.
