Abstract
PURPOSE:To attain excellent variable-speed reproduction by controlling tracking in reproduction by using a head that has a movable effective gap in the direction of the gap. CONSTITUTION:In addition to winding 2 forming the main coil, head yoke 1 has auxiliary coils 8-10 formed at hole parts 3-6 and the magnetic field of winding 2 is canceled by coils 8-10 to invalidate head gap 18 near holes 3-6. Consequently, the gap-directional movement of the effective gap of gap 18 is controlled to adjust tracking hold in reproduction mode. Therefore, variable-speed reproduction such as still reproduction that uses a rotary head can be carried out excellently.
