Abstract
A disk-cartridge-type adapter is shaped like a disk cartridge. The adapter has an insertion detector and a rotation detector. Power supply to a controller of the adapter is enabled when the adapter is inserted into a disk cartridge drive. Power supply to other parts of the adapter is enabled when a motor of the disk cartridge drive starts to rotate. This arrangement reduces the power consumption of the adapter.
Claims35
An adapter having a power source, a controller, and functional blocks controlled by the controller, the adapter being shaped like a disk cartridge so that the adapter is insertable into a disk cartridge drive, comprising:
- rotation detecting means for detecting the rotation of a motor of the disk cartridge drive, so that the controller may determine whether or not the disk cartridge drive is accessing the adapter and whether or not power from the-power source must be supplied to the functional blocks.
An adapter having a power source, a controller, and functional blocks controlled by the controller, the adapter being shaped like a disk cartridge so that the adapter is insertable into a disk cartridge drive, comprising:
- insertion detecting means for detecting complete insertion of the adapter into the disk cartridge drive, so that power supply from the power source is enabled on detecting the complete insertion and is disabled on not detecting the complete insertion;
- and
- rotation detecting means for detecting the rotation of a motor of the disk cartridge drive, so that the controller may determine whether or not the disk cartridge drive is accessing the adapter and whether or not power from the power source must be supplied to the functional blocks.
A disc cartridge type adapter comprising:
- a power supply unit;
- a processor adapted to be supplied with power from said power supply unit;
- a hub having a rotational axis of a disc drive, said rotational axis being fixedly fitted to said hub so that said hub rotates in accordance with the rotation of said rotational axis;
- a rotation detecting unit for detecting the rotation of said hub to output a signal each time said hub rotates by a predetermined number of rotations;
- and
- a control unit for controlling said power supply unit in such a way that a power supply is started from said power supply unit based on the result of the detection of the rotation of the hub by said rotation detecting unit.
An adapter having a power source and shaped like a disk cartridge so that the adapter is insertable into a disk cartridge drive, comprising:
- insertion detecting means for detecting complete insertion of the adapter into the disk cartridge drive, so that power supply from the power source is enabled on detecting the complete insertion and is disabled on not detecting the complete insertion, wherein:
- the insertion detecting means is so arranged to be pressed with a disk cartridge driving spindle of the disk cartridge drive;
- and
- power supply from the power source is enabled when the insertion detecting means is pressed with the disk cartridge driving spindle and is disabled when the insertion detecting means is not pressed with the same.
An adapter having a power source and shaped like a disk cartridge so that the adapter is insertable into a disk cartridge drive, comprising:
- insertion detecting means for detecting complete insertion of the adapter into the disk cartridge drive, so that power supply from the power source is enabled on detecting the complete insertion and is disabled on not detecting the complete insertion, wherein:
- the insertion detecting means is so arranged to be pressed with a write-protect detecting mechanism of the disk cartridge drive;
- and
- power supply from the power source is enabled when the insertion detecting means is pressed with the write-protect detecting mechanism and is disabled when the insertion detecting means is not pressed with the same.
An adapter having a power source and shaped like a disk cartridge so that the adapter is insertable into a disk cartridge drive, comprising:
- insertion detecting means for detecting complete insertion of the adapter into the disk cartridge drive, so that power supply from the power source is enabled on detecting the complete insertion and is disabled on not detecting the complete insertion, wherein:
- the insertion detecting means is so arranged to be pressed with a double-density detecting mechanism of the disk cartridge drive;
- and
- power supply from the power source is enabled when the insertion detecting means is pressed with the double-density detecting mechanism and is disabled when the insertion detecting means is not pressed with the same.
