Title: Level difference controller of video head
Inventor: HATTORI HIROKI
IPC: G11B5/588
Filed: 1984-10-16
Abstract: PURPOSE:To attain the fine control of level difference of a video head in a simple way and with extremely high accuracy, by controlling the amount of current supplied to a coil from a current supply means. CONSTITUTION:A resistance 5 and a capacitor 6 are connected in parallel to a coil 2, and each end at the other side of these resistance 5 and the capacitor 6 is grounded respectively. A current supply circuit 3 is connected to the coupling part P between a spring 1 and the coil 2 via a semifixed resistance 7. The amount of the current supplied to the coil 2 from the circuit 3 can be controlled with variation of the resistance value of the resistance 7. An end of a support part 4 is connected to the part P with the other end connected to the base stage of a video head. The part 4 varies in response to the variance of the part P. The spring 1 is expanded or compressed with control of the current flowing to the coil 2. Thus the part 4 connected to the part P has variance in response to the expansion or compression of the spring 1. Thus it is possible to control the difference of level of the video head.
