Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a magnetic disk recording/reproducing device used in various office automation equipment.

Conventional configurations and their problems In recent years, magnetic disk recording and reproducing devices have shown rapid progress as simple, highly reliable, and low-cost random access memories, with application fields such as office automation equipment and personal computers expanding. There is.

The general magnetic disk recording/reproducing apparatus mentioned above will be explained below with reference to the drawings.

FIG. 1 shows a conventional general magnetic disk recording/reproducing apparatus.

In FIG. 1, 1 is a magnetic disk for recording and reproducing information, and 2 is a magnetic disk cartridge that rotatably supports and stores the magnetic disk 1.

Reference numeral 3 designates a loader machine 3 which sets the magnetic disk cartridge 2 at the recording or reproducing position of the main body of the apparatus.

Reference numeral 4 denotes a magnetic disk rotation drive mechanism that rotates the magnetic disk 1 fully, and is driven by a motor 6 via a belt 6.

A magnetic head 7 is placed in contact with the surface of the magnetic disk 1.

Reference numeral 8 denotes a magnetic head moving mechanism for moving the magnetic head 7 in the radial direction of the magnetic disk 1.

Reference numeral 9 controls recording or reproducing on the magnetic disk 1 by the magnetic head 7, and a magnetic disk rotation drive mechanism 4. This is a control circuit section composed of an electric circuit that controls the magnetic head feeding mechanism 8.

The operation of the magnetic disk recording/reproducing apparatus configured as described above will be described below.

Without being separated, the magnetic disk cartridge 2 is set by the loading mechanism 3 at the recording/reproducing position of the main body of the apparatus.

Next, the magnetic disk 1 is rotated by the magnetic disk rotation drive mechanism 4.
rotates.

Then, the magnetic edge door is moved in the radial direction of the magnetic disk 1 by the magnetic head moving mechanism 8 and stops at a predetermined recording or reproducing position.

Next, information is recorded or reproduced on the magnetic disk 1 through the magnetic head γ according to an electric signal from the control circuit section 9.

FIGS. 2 and 3 show a magnetic head and a head carriage of a conventional magnetic disk recording/reproducing apparatus.

A concave surface 12 for holding the magnetic head 11 is formed at the end of the head carriage 10, and a concave surface 12 for holding the magnetic head 11 is formed from above.
1, the outer peripheral end surface 13 of the magnetic head 11 is
and between the end surfaces of the concave surface 12 of the helad carriage 10,
It is fixed and held by applying an epoxy adhesive 14.

By the way, in such a configuration, it is necessary to leave the magnetic head 11 alone for several tens of minutes until the epoxy adhesive 14 is completely cured so that the magnetic head 11 does not become misaligned.

Therefore, it has the disadvantage that it is difficult to balance the production line, such as loss of time to the next process.

Purpose of the Invention The present invention has been made in view of the drawbacks of the conventional examples, and an object thereof is to provide a magnetic disk recording and reproducing device that employs a magnetic head adhesive that takes a short drying time and has a well-balanced line. shall be.

Structure of the Invention In order to achieve the above object, the magnetic disk recording and reproducing apparatus of the present invention is capable of recording and reproducing information using a magnetic disk cartridge, which is constructed by rotatably supporting and housing a magnetic disk entirely within a molded resin case. a magnetic disk rotation drive mechanism that rotates the magnetic disk set at a recording/reproducing position by a loading mechanism for setting the magnetic disk; a magnetic head disposed so as to be in contact with the surface of the magnetic disk; A magnetic head sending mechanism for moving the magnetic disk in the radial direction, and a magnetic head for recording information on the magnetic disk by the magnetic head.
A control circuit section for controlling playback, a magnetic disk rotation drive mechanism, and a magnetic head transport mechanism, and a control circuit section for controlling reproduction, a magnetic disk rotation drive mechanism, and a magnetic head transport mechanism; This is a magnetic disk recording/reproducing device characterized by providing a widening slope.

With this configuration, it is possible to use a magnetic head adhesive that takes a short drying time.

DESCRIPTION OF THE EMBODIMENTS The overall structure of the magnetic disk recording and reproducing apparatus is as follows.
It is substantially the same as that shown in the drawings, and only the features of the present invention will be described below with reference to the drawings.

4 and 5 show an embodiment of the present invention.

A concave portion 12 for holding the magnetic head 11 and a slope portion 16 extending upward are formed at the end of the head carriage 10, and after the magnetic head 11 is placed from above, the outer peripheral end surface portion of the magnetic head 11 is 13 and the concave portions 12 and 7 of the herad carriage 10, and between the vanes 7 and the inclined portions 15, an ultraviolet curable adhesive 16 is applied, and ultraviolet rays 17 are irradiated from above to hold them fixed.

As described above, since the concave portion 12 of the head carriage 10 that holds the magnetic head 11 has the inclined portion 15 that spreads upward, when the ultraviolet ray 17 is applied after applying the ultraviolet curable adhesive 16, Due to the inclined portion 15 of the helad carriage 10, ultraviolet rays can be irradiated at the base portion of the concave portion 12 to completely cure the resin.

Effects of the Invention As described above, the magnetic disk recording/reproducing device of the present invention has a simple structure in which an inclined portion is provided that extends upward from the base of the concave surface of the head carriage in which the magnetic head is disposed, and can irradiate ultraviolet rays to the base of the adhesive. Therefore, it can be completely cured in a short time, and it also has great practical value, as it allows for line balance for the next process.
