Abstract
A data storage and retrieval system includes a head carriage unit having a working surface and multiple heads disposed at the working surface. The head carriage unit is adapted for rotational motion about an axis oriented substantially normal to the working surface. The system also includes a tape drive unit for moving a tape media past the working surface of the head carriage unit, the tape media having a width approximately equal to a width of the working surface of the head carriage unit. The multiple heads are configured to record multiple data tracks on or retrieve multiple data tracks from the tape media as the head carriage unit rotates while the tape media moves past the working surface of the head carriage unit.
Claims21
A data storage and retrieval system comprising:
- a head carriage unit having a working surface and a plurality of heads disposed at the working surface, the head carriage unit adapted for rotational motion about an axis oriented substantially normal to the working surface;
- and
- a tape drive unit for moving a tape media past the working surface of the head carriage unit, the tape media having a width approximately equal to the width of the working surface of the head carriage unit;
- wherein the plurality of heads are configured to record a plurality of data tracks on or retrieve a plurality of data tracks from the tape media as the head carriage unit rotates while the tape media moves past the working surface of the head carriage unit.
A data storage and retrieval method comprising:
- rotating a head carriage unit having a working surface about an axis oriented substantially normal to the working surface, the head carriage unit having a plurality of heads disposed at the working surface;
- moving a tape media past the working surface of the head carriage unit, the tape media having a width approximately equal to the width of the working surface of the head carriage unit;
- and
- as the head carriage unit rotates while the tape media moves past the working surface of the head carriage unit, recording a plurality of data tracks on or retrieving a plurality of data tracks from the tape media by the plurality of heads disposed at the working surface of the head carriage unit.
