Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust removing mechanism of a magnetic disk device, and more particularly, a dust removing member is disposed on the windward side of a head, and is brought into contact with the disk to swing together with a carriage. The floating and adhered dust on the top can be removed efficiently. Furthermore, if the function to maintain a fixed amount of lubricant, vibration control, and dehumidification / gas absorption can be achieved at the same time, the environment resistance of the device will be strengthened, and the vibration control of the carriage will improve the positioning accuracy of the device. (A large capacity is possible) A highly reliable device can be provided.

[0002]

2. Description of the Related Art In the dust removing mechanism disclosed in Japanese Unexamined Patent Publication No. 5-135562, a comb-shaped spoiler is arranged between discs with a predetermined gap between the discs. In this case, the dust floating on the disc can be captured, but the dust adhering to the disc cannot be removed.

In the dust removing operation disclosed in Japanese Unexamined Patent Publication No. 5-109222, the dust is removed using the head, so that the dust adhering to the disk can be removed, but the floating dust cannot be supplemented. Further, since the head is used, dust may be attached to the head, and in that case, in the worst case, a crash is induced.

[0004]

SUMMARY OF THE INVENTION The present invention uses a dust removing member that is brought into contact with a disc to remove both floating dust and adhering dust on the disc. If vibration, dehumidification, and gas absorption can be achieved at the same time, the environment resistance of the device will be strengthened, and the vibration damping of the carriage will improve the positioning accuracy of the device, resulting in high positioning accuracy (that is, large capacity is possible) and high reliability. A device can be provided.

[0005]

In order to achieve the above object, a special dust removing material is provided on the disk side of a beam projecting from an arm on the windward side of the head, and the special dust removing material is brought into contact with the disk. While doing so, dust is removed in accordance with the swing of the carriage.

Further, the above dust removing material contains a proper amount of lubricant, and a member capable of keeping the lubricant on the disk at a constant amount is used, a member having a vibration damping property is selected, and the inside is dried. Add agents or activated carbon.

As a result, it is possible to remove the floating dust and the adhered dust on the disk, enhance the environment resistance of the apparatus, and improve the positioning accuracy by damping the carriage.

[0008]

As described above, according to the present invention, the special dust removing member is arranged on the windward side of the head, and the floating dust and the attached dust can be efficiently removed by contacting the disc and swinging together with the carriage. . Furthermore, if you can also achieve a certain amount of lubricant retention function, vibration control, dehumidification and gas absorption at the same time,
Since the environment resistance of the apparatus is enhanced and the vibration of the carriage is suppressed, the positioning accuracy of the apparatus is also improved, and it is possible to provide a highly reliable apparatus with high positioning accuracy (that is, large capacity is possible).

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an apparatus to which the present invention is applied, FIG. 2 is a perspective view of a carriage, and FIG. 3 is a front view of the apparatus.

A plurality of disks 1 for recording information and a rotary shaft 4 are rotatably supported by a carriage 2, which is swingable, an arm arranged at right angles to the carriage 2, and the other end of the arm. In addition, a magnetic head 3 for recording / reproducing information on / from the magnetic disk 1 and a coil 5 for oscillating and driving the carriage 2 are arranged on the carriage 2 substantially symmetrically with the arm and the rotation axis. There is.

A special dust removing member 2b is provided on the disk side of the beam 2a protruding from the arm on the windward side of the head 3, and the beam 2a is brought into contact with the disk while the carriage 2 swings as shown in FIG. Remove dust.

Further, the special dust removing member 2b can be provided with another function at the same time. For example, the special dust removing member 2b contains a proper amount of lubricant for the disk 1, and the special dust removing member 2b has a function of holding a certain amount of lubricant. In addition, the carriage is damped to dampen the carriage. Further, by making the special dust removing member 2b hollow and enclosing a desiccant, activated carbon, etc. therein, it is possible to remove the gas and humidity of the air blown into the head 3.

As a result, if the floating dust and the adhering dust on the disk 1 can be removed efficiently, and further the function of holding a fixed amount of lubricant, damping, dehumidification and gas absorption can be achieved at the same time, the environment resistance of the device is enhanced. In addition, the damping of the carriage 2 improves the positioning accuracy of the apparatus, and it is possible to provide a highly reliable apparatus with high positioning accuracy (that is, a large capacity is possible).

Further, the present invention can be realized by the same principle even in the linear drive type.

[0016]

As described above, according to the present invention, the floating dust and the adhering dust on the disk can be efficiently removed,
Furthermore, if the function to maintain a fixed amount of lubricant, vibration control, and dehumidification / gas absorption can be achieved at the same time, the environment resistance of the device will be strengthened, and the vibration control of the carriage will improve the positioning accuracy of the device. It is possible to provide a highly reliable device.
