Title: Magnetic head core
Inventor: NISHIYAMA SHUNICHI
IPC: G11B5/23
Filed: 1987-04-20
Abstract: PURPOSE:To increase reproduction output by inclining the columnar crystals of a 'SENDUST(R)' film in the direction facing a gap or the opposite direction thereof with respect to a substrate surface on the slope of the recess of a half split body. CONSTITUTION:This core is constituted of the half split bodies 11 and 12. The half split body 11 has the recess 13. The 'SENDUST(R)' films 14, 15 are deposited on the joint surfaces of the half split bodies 11, 12 and these surfaces are joined to each other. One of the joint surfaces of the core constitutes the magnetic gap 17. The columnar crystals which are approximately perpendicular to the surface of the half split body 11 are adequate for the gap part 17. The columnar crystals inclined in the direction facing the gap part 17 or the opposite direction thereof with respect to the surface of the half split body are adequate for the slope 13a of the recess 13. The magnetic permeability in the intra-film direction of the film 14 is thereby increased. The reproduction output of the magnetic head is, therefore, increased.

A permanent magnet bar 15 is attached to the tip of a rigid plate 14 fixed to the other end of the frame 13. The bar 15 is set in a gap of an electromagnet 16 having a section face C and attached to the frame 13. When a tracking error signal is zero, no current flows to a coil 16c. Thus the bar 15 has no shift in the rotating direction of a disk 7. When the tracking error signal is not zero, a current flows to the coil 16c. Then the bar 15 shifts toward a track. As a result, the element 10 has a shift in the track direction.
