Head-cleaning device and head-cleaning method

1. A head-cleaning device that cleans a surface of a head for reading and writing data from/to a medium, comprising:

a cleaning unit configured to move in parallel with grooves provided in the surface of the head while abutted to the grooves, and thereby cleans the surface of the head.

2. The head-cleaning device according to claim 1 , wherein

the cleaning unit comprises a brush configured to abut to the grooves provided along a predetermined direction of the surface of the head, and move in parallel with the grooves.

3. The head-cleaning device according to claim 1 , further comprising:

a lever unit and two arm units configured to support and move the cleaning unit; wherein

the lever unit moves in a circular-arc trajectory, and

the two arm units move in left-right symmetry by interlocking and rotation of two cogs provided to each section of the lever unit that supports the cleaning unit in conjunction with movement of the lever unit, and move the cleaning unit in parallel.

4. The head-cleaning device according to claim 3 ,

wherein, after cleaning of the head has ended, the cleaning unit moves to a predetermined standby point by the movement of the lever unit and the two arm units, and

by making contact with a predetermined member when moving to the predetermined standby point, the cleaning unit is changed from an angle where the cleaning unit abuts substantially perpendicular to the surface of the head to an angle where the cleaning unit does not abut to the surface of the head and is substantially parallel thereto.

5. The head-cleaning device according to claim 3 , further comprising:

a base member configured to support the two arm units, the base member having two protrusions secured thereto, wherein

each of the two arm units has one long hole part, each of the two protrusions is fitted to the long hole part of the two arm units; and

when the two arm units move in left-right symmetry, each of the two protrusions slides in the long hole part.

6. The head-cleaning device according to one of claim 3 , wherein

the lever unit includes a protrusion part secured to a tip part that supports the cleaning unit;

the cleaning unit includes a long hole part for fitting the protrusion therein in a connection part of the cleaning unit that connects to the tip part of the lever unit; and

when the lever unit moves in a circular-arc trajectory, the protrusion slides in the long hole part.

7. The head-cleaning device according to claim 5 , wherein

after cleaning of the head has ended, the cleaning unit is moved by the lever unit and the two arm units to a vicinity of the base member as a standby point, where the cleaning unit is stored next to the base member; and

the cleaning unit is stored so that the cleaning unit does not protrude from the base member.

8. The head-cleaning device according to claim 5 , wherein

at least one of the two arm units includes another long hole part provided separately from the long hole part;

the base member includes another protrusion provided separately from the protrusion and corresponding to said another long hole part; and

when the two arm units move in left-right symmetry, in conjunction therewith said another protrusion fits into said another long hole part and slides therein.

9. A head-cleaning method performed by a head-cleaning device that cleans a surface of a head for reading and writing data from/to a medium, wherein

the head-cleaning device moves a predetermined cleaning unit in parallel with grooves provided in the surface of the head while abutted along the grooves, and thereby cleans the surface of the head.
