[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic disk carriage device, and more particularly to miniaturization thereof.

[0002]

BACKGROUND OF THE INVENTION Figure 2 is a diagram viewed from above the conventional magnetic disk carriage device, 1 disc cartridge in FIG, 2 is a magnetic disc platter disposed in the disc cartridge 1, 3 magnetic heads, Reference numeral 3a is an information read / write unit provided at the tip of the magnetic head 3, and 4 is a head support sliding unit attached to the base 3b of the magnetic head 3 and connected to the head drive unit 5. A motor or the like is generally used as the head drive device. A combination of a lead screw and a nut for converting a rotary motion into a linear motion is used as the head supporting sliding part. 3 is an enlarged perspective view of the support head 3, which is composed of a first magnetic head 31 and a second magnetic head 32, and the magnetic heads 31 and 32 are connected to each other at the base 3b.

In the magnetic disk carriage device as described above, the magnetic head 3 slides in the radial direction of the magnetic disk disk 2 by the head drive device 5 via the head supporting slide portion 4. At this time, the magnetic disk disk 2 is arranged between the first magnetic head 31 and the second magnetic head 32,
The reading / writing unit 3a reads and writes information by being held via a gap 32 and a rotation center 6 about a rotation center 6.

[0004]

Since the conventional magnetic disk carriage device is constructed as described above, the head supporting slide portion 4 is arranged near the read / write portion of the magnetic head when reading / writing information. Influences reading and writing of information. For this reason, the head supporting slide portion 4 must be arranged so as not to overlap the magnetic disk disc 2. Therefore, there is a problem that the magnetic disk carriage device becomes large in scale because the head supporting sliding portion 4 is required to be added in length for the stroke of moving the magnetic head 3 back and forth.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a magnetic disk carriage device which can be miniaturized.

[0006]

In a magnetic disk carriage device according to the present invention, a read / write section of a magnetic head and a head supporting slide section are arranged at positions facing each other with respect to a rotation center of a magnetic disk disk. Is.

[0007]

Since the head supporting slide portion in this invention is arranged apart from the read / write portion of the magnetic head, it should be arranged so as to overlap a part of the magnetic disk without affecting the reading / writing of information. Therefore, the magnetic disk carriage device can be downsized by the amount of this overlap.

[0008]

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG.
In FIG. 3, the information read / write unit 3a of the magnetic head 3 and the head support sliding unit 4 are arranged at positions facing each other with respect to the rotation center 6 of the magnetic disk disk. Reference numeral 7 denotes a hole provided in the central portion of the magnetic head 3, which is opposed to the rotation center 6 of the magnetic disk disk and prevents the rotation shaft mechanism from overlapping.

In the magnetic disk carriage device having such a structure, since the reading / writing section 3a is separated from the head supporting sliding section 4, the head supporting sliding section 4 may affect the reading / writing of information. Absent. Therefore, the head support sliding portion 4 can be arranged close to the center of rotation of the magnetic disk disc 2 without taking into account the stroke of moving the magnetic head 3 back and forth. That is, the head supporting sliding portion 4 and a part of the magnetic disk disc 2 can be arranged so as to overlap each other, and the magnetic disk carriage device can be downsized by the amount of overlap.

[0010]

As described above, according to the present invention, a magnetic head that slides on a magnetic disk disk to read and write information, and a head support slider that is connected to the magnetic head and slides the magnetic head. In a magnetic disk carriage device having a moving part, the read / write part of the magnetic head and the head supporting sliding part are arranged at positions facing each other with respect to the center of rotation of the magnetic disk disk, so that the head supporting sliding part overlapping a portion of the part and the magnetic disc platter, it is possible to miniaturize the whole, the head driving instrumentation integrated with the supporting sliding portion with which
Since the device can also be separated from the reading and writing section,
Protection from mechanical disturbances and electromagnetic noise
Protects and adheres closely to the magnetic disk surface of the read / write section
Thus, a magnetic disk device capable of
