发明名称 Vertical recording magnetic head
摘要 A vertical recording magnetic head is disposed for movement close to or into sliding contact with a vertical recorded magnetic medium for purpose of magnetic recording and playback. To prevent the influences of external magnetic field upon a recording or reproduced magnetic field, a main magnetic pole of the head is surrounded by a block of a magnetizable material which exhibits a high permeability, which serves as a magnetic shield.
