Abstract
A disc device for recording and/or reproducing information with respect to a disc having flexibility includes a head for writing and/or reading, the head being disposed below the disc; a disc rotating section which rotates the disc; and a head retracting section which retracts the head to a retracted position where contact with the disc is avoidable, based on a judgment that power supply to the disc device is cut off.
Claims8
A disc device for recording and/or reproducing information with respect to a disc having flexibility, the disc device comprising:
- a head for writing and/or reading, the head being disposed below the disc;
- a disc rotating section for rotating the disc;
- and
- a head retracting section for retracting the head to a retracted position where contact with the disc is avoidable, based on a judgment that power supply to the disc device is cut off.
A disc device for recording and/or reproducing information with respect to a disc having flexibility, the disc device comprising:
- a head for writing and/or reading, the head being disposed below the disc;
- a disc rotating section for rotating the disc;
- and
- a head retracting section for retracting the head to a retracted position where contact with the disc is avoidable, based on a judgment that a rotational speed of the disc falls below a predetermined threshold value.
A disc device for recording and/or reproducing information with respect to a disc having flexibility, the disc device comprising:
- a head for writing and/or reading, the head being disposed below the disc;
- a disc rotating section for rotating the disc;
- and
- a head retracting section for retracting the head to a retracted position where contact with the disc is avoidable in a condition that the disc is likely to be contacted with the head resulting from lowering of a rotational speed of the disc.
