Abstract
A magnetic head without an erase head, which includes a substantially U-shaped magnetic core with opposed end faces of a pair of legs forming a gap; and a magnetic material attached to one of the end faces to form a write read head with the other end face to write and read data from a recording medium. The magnetic material has a saturated flux density lower than that of the magnetic core. A read track width made by the magnetic material and the other end face is smaller than a write track width made by the opposed end faces.
Claims5
A wide-write, narrow-read, single-gap magnetic head comprising:
- a substantially U-shaped magnetic core with opposed end faces of a pair of legs having a substantially equal width;
- and
- a magnetic material attached to one of said end faces to form a read gap with the other end face,
- said magnetic material having a saturated flux density lower than that of said magnetic core, and
- said read gap having a read track width smaller than a write track width made by said opposed end faces.
