Record regenerator

Abstract

A recording and reproducing device, the device can make the height of a guide shaft easily adjustable and to deal with downsizing. The guide shaft is provided with notches at both ends. The notches are formed to a semi-circular shape when viewed from an axial direction and are formed with planes parallel to the axial direction. The planes are pressed by first energizing portions of a leaf spring. An adjusting screw is screwed into a threaded hole penetrating the planes. The height positions at both ends of the guide shaft are adjusted by the degree of tightening of the adjusting screw. Since the adjusting screw is screwed into the threaded hole of the guide shaft in the manner described above, a smaller installation space is needed and the downsizing of the device is made possible.

Description

technical field [0001] The present invention relates to a recording and reproducing device, and particularly relates to a recording and reproducing device capable of adjusting the head height for reading and writing data on a recording medium. Background technique [0002] For example, in a recording device loaded with a disc-shaped recording medium, an optical head (head) (optical head) consisting of a laser-type optical pickup (pick up) moves in the radial direction of the disc to Data is read from or written to the recording medium. In such a recording and reproducing device, when a tray carrying a disc-shaped recording medium is inserted into the device, the disc-shaped recording medium in the tray will be clamped by a turn table, and then the optical head will be directed to the guide axis to perform a seek action in the radial direction. [0003] In such a recording and reproducing device loaded with a disc-shaped recording medium, in order to correctly read the data...

Problems solved by technology

[0007] However, in the recording and reproducing device described in the above-mentioned publication, the adjustment screw contacts the outer circumference of the guide shaft formed by the round bar from the side, and the head of the adjustment screw presses the outer circumference of the guide shaft from above to compress the outer circumference of the guide shaft. The coil spring between the frame and the frame, so the compression of the coil spring can be changed by the tightening state of the adjustment screw screwed around the guide shaft to adjust the height of the guide shaft to the frame. Therefore, the adjustment mechanism of the guide shaft The structure will become larger, and the installation space of the adjustment mechanism will become larger, and there is a problem that it cannot cope with the miniaturization of the recording and reproducing device.

[0008] In the recording and reproducing device described in the above publication, the coil spring between the guide shaft and the frame formed by the round bar is in a compressed state, and the compression of the coil spring is changed by adjusting the tightening state of the screw, so as to compress the frame. Since the height of the guide shaft is adjusted, the minimum adjustable height of the guide shaft is too high, and there is a problem that it cannot cope with the thinning of the recording and reproducing device.
