ABSTRACT:
A magnetic head for vector recording/playing capable of recording in multiple directions to increase recording density. In the magnetic head according to the present invention, a body is formed to have four poles, each of which is wound with a coil. Accordingly, 3-bit data, in which magnetic domains are arranged in eight directions may be recorded/reproduced, to thereby record a large amount information in one recording area of the track, and reduce the data transfer rate.
