調整の諸々の作業性が極めて悪かつた。 As is well known, magnetic recording is a type of magnetic recording in which recording and reproduction can be performed by bringing a magnetic head into contact with a magnetic disk called a disk recorder or sheet recorder, for reasons such as easy slow motion, quick motion, or reverse playback. Reproducing devices are now being put into practical use. In order to perform the recording or reproducing operation smoothly, it is necessary to maintain good contact between the magnetic head and the magnetic disk at all times, and for this reason various magnetic head devices have been proposed. , these have a configuration that is extremely difficult to adjust to maintain the above-mentioned contact state appropriately. Generally, the magnetic head is mounted parallel to the recording or reproducing track of the magnetic medium and aligned with the width direction of the track.
The installation is adjusted to prevent changes in the thickness of the guard due to track pairing and narrowing of the tracking range, and the amount of protrusion is adjusted to obtain the specified image signal output at a high level. will also be held. Furthermore, in order to obtain a high level of image signal output, the vertical angle of the magnetic head with respect to the magnetic tape and the angle of the magnetic head in the running direction are adjusted, and in order to increase high frequency reproduction sensitivity and avoid overmodulation phenomenon, The slope of the gap of the magnetic head relative to the magnetic tape (azimuth)
adjustments will be made. Conventionally, these adjustments were made using completely separate adjusting members from different directions, which had the disadvantage that adjusting one would significantly disturb the adjusted state of the other. The adjustment work is extremely troublesome because it has to be done from various directions, such as from the bottom, and furthermore, the adjustment device is assembled one by one onto the headblock.
Therefore, the workability of installing the magnetic head device and making the various adjustments described above was extremely poor.
