IPC: G11B5/127
Filed: 1988-01-26
Abstract: PURPOSE:To prevent a magnetic flux from being leaked near the gap of a coil window and to improve head efficiency by causing the length of a track specifying channel in a core half body, in which the coil window is provided, to be longer than the length of the track specifying channel in the core half body, where the coil window is not provided.

Namely, a length Lb of the track width specifying channel in the core half body B is made long to a length La of the track width specifying channel in a core half body A to have the coil window 5. Thus, since a facing surface is not formed in the tip parts (gap approaching parts) of magnetic layers 2a and 2b, the leaking magnetic flux goes to be minimum and the efficiency of the head can be improved.
