发明名称 Magnetic head with high reliability of the data protection, magnetic disk apparatus including the magnetic head and the method of recording information on the magnetic disk apparatus without miserasing the previously recorded data
摘要 There are provided a magnetic head and a magnetic disk apparatus wherein an upper magnetic pole is so shaped that, at a position where skew angle is maximum, the maximum of its projected length in the radial direction of a magnetic disk is not more than the track pitch of the magnetic disk, whereby acceleration of thermal relaxation of information recorded on adjacent tracks is obviated even in an area where the skew angle is large.
