Abstract
According to one embodiment, there is provided a disk device including a head, a disk, a first motor, and a first circuit. The disk has a recording surface. The first motor causes the head to seek along the recording surface. The first circuit can switch between a first state and a second state. The first state is a state where a current path of the first motor is electrically cut off from a first electricity storage unit. The second state is a state where the current path of the first motor is electrically connected to the first electricity storage unit.
Claims20
A disk device comprising:
- a head;
- a disk having a recording surface;
- a first motor that causes the head to seek along the recording surface;
- and
- a first circuit that can switch between a first state and a second state, the first state being a state where a current path of the first motor is electrically cut off from a first electricity storage unit, the second state being a state where the current path of the first motor is electrically connected to the first electricity storage unit.
A disk device comprising:
- a head;
- a disk having a recording surface;
- a first motor that causes the head to seek along the recording surface;
- an electricity storage terminal that can be connected to the first electricity storage unit via a power line;
- and
- a first circuit that can switch between a first state and a second state, the first state being a state where a current path of the first motor is electrically cut off from a first electricity storage unit via the electricity storage terminal and the power line, the second state being a state where the current path of the first motor is electrically connected to the first electricity storage unit via the electricity storage terminal and the power line.
An information processing apparatus comprising:
- a host including an electricity storage unit;
- a first disk device that includes a first head, a first disk having a first recording surface, a first motor that causes the first head to seek along the first recording surface, and a first circuit that can switch between a first state and a second state, the first state being a state where a current path of the first motor is electrically cut off from the electricity storage unit via a first power line, the second state being a state where the current path of the first motor is electrically connected to the electricity storage unit;
- and
- a second dash device that includes a second head, a second disk having a second recording surface, a second motor that causes the second head to seek along the second recording surface, and a second circuit that can switch between a third state and a fourth state, the third state being a state where a current path of the second motor is electrically cut off from the electricity storage unit via a second power line, the fourth state being a state where the current path of the second motor is electrically connected to the electricity storage unit.
An information processing apparatus comprising:
- a host;
- and
- a disk device that can be connected to the host,
- wherein the disk device includes:
- a head;
- a disk having a recording surface;
- a first motor that causes the head to seek along the recording surface;
- and
- a first circuit that can switch between a first state and a second state, the first state being a state where a current path of the first motor is electrically cut off from a first electricity storage unit, the second state being a state where the current path of the first motor is electrically connected to the first electricity storage unit.
