Abstract

(57) [Summary] [Purpose] To reduce the size of a magnetic head carriage device. [Structure] The read/write section 3a of the magnetic head 3 and the head support sliding section 4, which is connected to the magnetic head and causes the magnetic head to slide, are arranged at opposite positions with respect to the rotation center 6 of the magnetic disk disc 2. are doing. Thereby, a portion of the head support sliding portion and a portion of the magnetic disk disk are overlapped, and the overall size can be reduced.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to magnetic disk carriage devices, and in particular to miniaturization thereof. It is.

0002

[Conventional technology]

Figure 2 is a configuration diagram of a conventional magnetic disk carriage device viewed from above. 1 is a disk cartridge, and 2 is a magnetic disk placed on the disk cartridge 1. 3 is a magnetic head, and 3a is an information reader provided at the tip of the magnetic head 3. The writing section 4 is attached to the base 3b of the magnetic head 3 and connected to the head drive device 5. This is the head support sliding part. FIG. 3 is an enlarged perspective view of the support head 3, showing the first magnetic head 31 and the second magnetic head 31. magnetic head 32, and both magnetic heads 31 and 32 are connected at the base 3b. .

0003 In the above-mentioned magnetic disk carriage device, the head is The magnetic head 3 is slid in the radial direction of the magnetic disk disk 2 by the head drive device 5. Ru. At this time, the magnetic disk disk 2 has a first magnetic head 31 and a second magnetic head 32. Between the two magnetic heads 31 and 32, the magnetic heads are held through a gap and rotated about the rotation center 6. In turn, the read/write unit 3a reads and writes information.

0004

[Problem that the idea aims to solve]

Conventional magnetic disk carriage devices are configured as described above, so information When reading and writing the magnetic head, the head support sliding part 4 is placed near the reading and writing part of the magnetic head. This affects reading and writing of information. For this reason, the head support sliding portion 4 must be placed on the magnetic disk disk 2 so that they do not overlap. Therefore, The length is the length of the head support sliding part 4 added to the stroke of the magnetic head 3 moving back and forth. The problem is that the magnetic head carriage device becomes large-scale. was there.

[0005] This idea was made to solve the problems mentioned above, and it is possible to make it smaller. The object of the present invention is to obtain a magnetic head carriage device that has the following characteristics.

[0006]

[Means to solve the problem]

The magnetic disk carriage device according to this invention has a read/write section of a magnetic head and a head. The pad support sliding portion is located at a position opposite to the rotation center of the magnetic disk disk. It is something that

[0007]

[Effect]

The head support sliding part in this invention is located apart from the read/write part of the magnetic head. Because of the The magnetic head carriage device can be placed partially overlapping. can be made smaller.

[0008]

【Example】

Example 1. An embodiment of this invention will be described below with reference to the drawings. In FIG. 1, the magnetic head 3, the information reading/writing section 3a and the head support sliding section 4 are connected to the rotation center 6 of the magnetic disk disk. are placed opposite to each other. 7 is provided at the center of the magnetic head 3. The hole faces the rotation center 6 of the magnetic disk disk, avoiding overlap with the rotation axis mechanism. It is for.

[0009] In a magnetic disk carriage device with such a configuration, the reading/writing section 3a is a head support. Since it is separated from the holding and sliding part 4, the head supporting sliding part 4 is also used when reading and writing information. has no influence. For this reason, the head support sliding portion 4 is attached to the magnetic head 3. Contact the center of rotation of the magnetic disk disc 2 without taking into account the stroke of moving back and forth. Can be placed close together. That is, the head support sliding part 4 and a part of the magnetic disk disc 2 are They can be arranged one on top of the other, and the magnetic disk carriage device can be made smaller by the amount of overlap.

0010

[Effect of the idea]

As mentioned above, according to this invention, information is read and written by sliding on a magnetic disk disk. A magnetic head that slides, and a head that is connected to this magnetic head and that slides the magnetic head. In a magnetic disk carriage device equipped with a supporting sliding part, reading and writing of the magnetic head The position where the sliding part and the head support sliding part are opposite to each other with respect to the rotation center of the magnetic disk disk. By placing a part of the head support sliding part and part of the magnetic disk disk in a As a result, a magnetic disk device that can be made smaller as a whole can be obtained.
