This is the first magnetic head mounting device of this type ever.
The structures shown in a and b in the figure are known. In FIGS. 1a and 1b, 1 is a chassis, 2 is a slide plate that is regulated in the left and right direction between the chassis 1 and can be slid in the front and back direction via a steel ball, etc., and 3 is a magnetic head 4. This head spacer is fixed to the slide plate 2 and has fixed bosses 3a and 3d that can be fixed at a specified height in relation to the cassette half. 5 is an azimuth adjustment spring that allows adjustment of the inclination of the head.

の位置関係がズレるという欠点があつた。 In particular, the longitudinal position of the head is important in relation to tape touch; if the head is pushed in too far, wow and flutter will worsen, and if the magnetic head is pushed in too little, the frequency characteristics will deteriorate, so the position of the magnetic head is always Although we want to keep it constant, the difference in the mounting hole and screw diameter can cause variations in installation, and while repeating the operation, the positional relationship between the magnetic head and tape may change due to vibrations and shocks. It had the drawback of being misaligned.

As described above, according to this invention, there is a head mounting plate for fixing the magnetic head, a fixing boss for fixing the head mounting plate at a predetermined height, and a fixed boss for fixing the head mounting plate at a predetermined height. The fixing boss and the pressing boss are integrally molded and attached to the head slide plate, so one side of the fixed magnetic head can be adjusted by using a spring to adjust the inclination. Although it is in a semi-fixed state and the mounting hole diameter is larger than the screw diameter, the longitudinal positioning of the magnetic head is kept constant, solving the problem of head displacement due to installation variations, vibrations during operation, and shocks, making it stable. Tape touch can be performed.
