Claims

[Claims for Utility Model Registration] A motor that rotationally drives a drive shaft that rotates a magnetic disk, and a motor that holds a magnetic head and reciprocates in the radial direction of the magnetic disk while bringing the magnetic head into contact with the magnetic disk. a head arm for recording and reproducing information on the magnetic disk of the lever; a power mechanism having a deceleration mechanism for reducing the rotational speed of the drive shaft and converting the rotation of the drive shaft into reciprocating motion of the head arm; a signal circuit section mounted on a substrate and configured to record and reproduce signals from the magnetic head on the magnetic disk;
A drive control circuit section for controlling the rotational drive of the motor; A magnetic recording and reproducing apparatus comprising: a base substrate to which the motor, the head arm section, and the power mechanism are attached; and a base substrate for holding the base substrate; A frame body having a mounting part to be attached to the device is made of a separate member and is made into a separate body, and the main body part of the optical sensor for detecting the optical signal used in the signal circuit part and the drive control circuit part is inserted. A magnetic recording/reproducing device characterized in that a sleeve for mounting the optical sensor is integrally molded on the frame, and the sleeve is provided with a storage recess for positioning and a long lead hole into which a lead wire is introduced.
