Title: Magnetic head
Inventor: MATSUDA WAKATAKE
IPC: G11B5/02
Filed: 1981-03-31
Abstract: PURPOSE:To improve electromagnetic conversion efficiency, by providing a main magnetic pole and a reflux magnetic pole having a prescribed magnetic field intensity, on a vertical magnetizing and recording magnetic head. CONSTITUTION:A vertical magnetizing and recording magnetic head consists of a main magnetic pole 10 and reflux magnetic poles 11, 12 which have branched into 2 parts, and a coil 13 is wound around the main magnetic pole 10. A recording medium is constituted of a full magnetic substrate 5, a magnetic substance layer 6 and a vertical magnetizing magnetic substance layer 7. The electromagnetic conversion efficiency is improved since a closed magnetic path returning to the reflux magnetic pole 11 or 12 is formed through the magnetic layer 6 of the recording medium from the main magnetic pole. Also, when intensity of the reflux magnetic poles 11, 12 is set to 0.17 of intensity of the main magnetic pole, no influence by the reflux magnetic poles 11, 12 is exerted.

Filed: 1978-04-24
Abstract: PURPOSE: To prevent uneven magnetization of the transformer core by overlapping a DC voltage over the AC voltage applied at the primary of transformer or supplying a DC current through additional winding for the DC current at the secondary of transformer.  
     CONSTITUTION: Assuming the conducting phase of each thyristor in semi-bridge inverter comprising the thyristors 25, 26 is 180°, the voltage applied at the primary of transformer 13 becomes rectangular. Assuming the DC voltage 23 is E1 and the DC voltage 24 is E2 the DC voltage applied at the primary of transformer 13 is shown by (E1-E2)/2, thereby when determining said DC voltage (E1-E2)/2 such that the primary equivalent in the current detector 21 and the detected level in the current detector 18 go to zero, the uneven magnetization of transformer 13 can be prevented by controlling the voltage E2 of DC power source 24.
