Abstract

PURPOSE:To control the protruding quantity of a magnetic head toward a recording medium with high accuracy by bringing a disk supporting body into contact with part of the recording medium running plane of a recording medium guiding body when the guiding body is brought nearer to the disk supporting body by means of a guiding body moving means and positioning the guiding body to the supporting body. CONSTITUTION:The required protruding quantity of a magnetic head 11 toward a recording medium 13 is decided by using a reference plane 17a and, by bringing the reference plane 17a into contact with the running plane 26e in which the recording medium 13 is guided, a disk supporting body 17 and recording medium guiding body 26 are positioned to each other. Therefore, the protruding quantity of the magnetic head 11 from the reference plane 17a becomes the protruding quantity of the recording medium 13 from the running plane 26e in which the recording medium 13 is guided as it is and the protruding quantity of the magnetic head toward the recording medium can be controlled with high accuracy.

Conventional technology Conventionally, when performing high-density recording in this type of magnetic recording/reproducing device, a so-called helical scan method was used in which a straight recording track was formed at a certain inclination with respect to the longitudinal direction of the recording medium. . When playing this method,
A magnetic head scans the recording track and converts the recorded content into an electrical signal. Therefore, in order to make this helical scan possible, in a magnetic recording/reproducing device, a magnetic head is attached to the side of a rotating cylinder that can scan in a direction with a certain inclination to the feeding direction of the recording medium, and the recording medium is moved into the rotating cylinder. It is configured to be wrapped around the side of the However, the above configuration requires a sophisticated loading mechanism and tape path for winding the recording medium around the rotating cylinder, resulting in a complicated structure.

In the figure, 1 is a rotary drive shaft, 2 is a magnetic head 3 with four pieces 9
A rotating cylinder for mounting at 0-degree intervals, 4 is a recording medium. Reference numeral 5 denotes a recording medium guide plate provided at opposing positions with the rotating cylinder 2 and the recording medium 4 interposed therebetween, and has long grooves along the tape running direction 7 in portions opposing both ends 4a14b of the recording medium 4 in the width direction. 5 aN 5 b. Presser plates 6 are provided at both ends of the recording medium guide plate 5 in the recording medium running direction 7, facing each other with the recording medium in between, and convex portions 6a, 6 are provided at both ends in the recording medium width direction.
The convex portion easeb provided at the b end is configured to fit into the long grooves 5a and 5b of the recording medium guide plate 5. The rotary cylinder 2 rotates in the direction 8, and signals are recorded on the recording medium 4 in an arcuate track of approximately 90 degrees as shown in FIG.

In the above configuration, the recording medium 4 traveling within the recording medium guide plate S and the rotating cylinder 2 is pressed by the press plate 6 at both ends of the recording medium guide plate S, and both ends 4as4b of the press plate 6 are pressed against the recording medium guide plate S. Since the recording medium 4 is pushed and bent to the side, an arcuate track can be formed without deforming the recording medium 4 by the magnetic head 3 of the rotary cylinder 2 or damaging both ends thereof.

Problems to be Solved by the Invention According to this example, the recording medium 4 is guided along the recording medium guide plate 5, and since the magnetic head 3 is attached to the rotary cylinder 2, there is a gap between the rotary cylinder 2 and the recording medium guide plate. In order to take out the recording medium 4 sandwiched between the magnetic heads 5 and 5, it is necessary to separate the recording medium guide plate 5 from the rotating cylinder 2. Therefore, in order to maintain a highly accurate relationship between the recording medium 4 and the magnetic head 3, it is necessary to move the recording medium guide plate 5 away from the rotating cylinder 2. On the other hand, it is necessary to position the recording medium guide plate 5 with high precision.

However, in the conventional example described above, since the magnetic head 3 is attached to the rotating cylinder 2, the amount of protrusion of the magnetic head 3 toward the recording medium 4 is controlled with respect to the rotating cylinder 2. On the other hand, when positioning the recording medium guide plate 5, it is impossible to bring a part of the recording medium guide plate 5 into contact with the rotary cylinder 2. As a result, in the conventional helical scanning method, the amount by which the magnetic spatulas 1!3 press against the recording medium 4 could be directly controlled by the amount of protrusion from the outer periphery of the rotating cylinder 10, as shown in FIG. In this example, the control will be indirect and it will be very difficult to manage it with high precision. Variations in the amount of protrusion of the magnetic head 3 toward the recording medium 4 directly result in unstable head output, which greatly affects image quality.

The operation of the magnetic recording/reproducing apparatus having such a configuration will be described below. FIG. 1 shows the recording or reproducing state, and FIG. 3 shows the state in which the magnetic tape 13 can be taken out. When the magnetic tape 13 is set between the tape guide 26 and the disk support 17 in the state shown in FIG. 3, the tape loading mode is entered and the tape guide 26 is guided by the guide shaft 24, 25 by a drive motor (not shown) and the disk It starts moving in the direction approaching the support body 17. Eventually, the magnetic tape 13 comes into contact with the magnetic tape 13, and the magnetic tape 13 is moved together with the tape guide 26 in the direction of the disk support 17.

The drive motor also stops and the tape guide 26
and the disk support 17 have the positional relationship shown in FIG. At this time, the protrusion 17b, which has a reference plane when adjusting the protrusion amount of the magnetic head 11 on the same plane as the protrusion 17a, does not face the tape guide surface 26c of the tape guide 26 as shown in FIG. There is no contact with the surface 26c. The magnetic tape 13 is guided by the tape guide surface 26d-26cm26d of the tape guide 26, and its lower end runs in the g direction along the tape lead portion 26a. FIG. 4 is a diagram of the magnetic tape 13 viewed from the recording surface.

a recording medium guide for guiding the recording medium so that the recording medium runs on a plane parallel to a plane of rotation of the magnetic head; and a head disk to which the magnetic head is attached is rotatable about the rotation drive shaft. The disk support includes a supporting disk support, and a guide moving means for moving the recording medium guide close to and away from the disk support, and the disk support has a reference plane parallel to the rotation plane of the magnetic head, This reference plane is located further above the upper end of the recording medium, and when the recording medium guide is brought close to the disk support by the guide moving means, the reference plane A magnetic recording/reproducing device characterized in that the recording medium guide is positioned on the disk support by contacting a part of a running plane.
