Abstract: PURPOSE:To simplify production and to enable high-density recording- reproduction by forming a write-read head core and an erasing core, then forming the groove of a narrow track, and embedding a nonmagnetic substance in the groove. CONSTITUTION:The write-read gap 3 is formed on the first magnetic substance core 1 in the form of a block or a bar, and the first magnetic substance core 1 and the second magnetic substance core 2 are welded by high-m.p. glass 17. The groove of the narrow track is formed on the integrated first magnetic substance core 1 and the second magnetic substance core 2 so that the width of the reproducing track is controlled to TW1. Then a couple of thin platy spacers 4 and 5 are bonded by a resinous adhesive or low-m.p. glass and embedded in the groove. Under such conditions, the material is sliced and ground to form a write-read magnetic head having the prescribed core width. An erasing head is formed in the same way with the third magnetic substance cores 7 and 7', erasing gaps 9 and 10, the fourth magnetic substance cores 8 and 8', spacers 11-13, and high-m.p. glass 18.

Filed: 1990-02-28
Abstract: PURPOSE:To enable a driving center of a voice-coil motor to approach a centroid position of a carriage and to raise a resonance frequency of the carriage and to construct a stable control system by arranging a magnet narrowed in width close to the centroid position of the carriage. CONSTITUTION:The width Wm of the magnet 3 to be fitted to the voice-coil motor 1 is settled with a width Wy of a yoke 2 constituting a magnetic circuit to satisfy their relation of Wm < Wy. Then, the magnet 3 is arranged close to the centroid position of the whole carriage system including a head arm 9, etc. By this method, magnetic flux from the magnet 3 becomes the max. in the center of the width Wm, viz. the driving center A, thus approaching the centroid position B more than ever by Wr/2 - Wm/2. Consequently, the driving center A and the centroid position of the whole carriage are closed up, and the resonance frequency is raised so that the resonance level can be lowered.
