Claims

[Scope of utility model registration request]

It is used in a recording/reproducing device for magnetic disks, etc., and has a head feeding mechanism that can move forward and backward in the radial direction of the disk, and the head feeding mechanism is operated by engaging a feeding screw and a single shaft. A head moving mechanism characterized in that the degree of engagement between the feed screw and the shaft can be adjusted using a push screw.
