Abstract
A data storage device is disclosed comprising a reel that is rotated for a first interval in order to expose a first frame of a magnetic tape to a head. The head is actuated in a first and second dimensions over the magnetic tape in order to access the first frame of the magnetic tape.
Claims20
A data storage device comprising:
- a magnetic tape;
- at least one reel;
- a first actuator configured to wind the magnetic tape around the reel;
- a first head configured to access the magnetic tape;
- a second actuator configured to actuate the first head over the magnetic tape in a first dimension;
- a third actuator configured to actuate the first head over the magnetic tape in a second dimension;
- and
- control circuitry configured to:
- control the first actuator to rotate the reel for a first interval in order to expose a first frame of the magnetic tape to the first head;
- and
- while the magnetic tape remains stationary, control the second and third actuators to actuate the first head in the first and second dimensions over the magnetic tape in order to access the first frame of the magnetic tape.
