摘要： Improvements in the perpendicular magnetic recording and reproducing head of the type in which a main magnetic pole and an auxiliary magnetic pole are arranged as a unitary structure on one side of a magnetic recording medium. Problems are solved in relation to pseudo pulses in the output signals and change in the level, contributing to improving the sensitivity for recording and reproduction. The magnetic head is used for perpendicular VTR's. The perpendicular magnetic recording and reproducing head of the invention comprises a support block which consists of a main magnetic pole, a non-magnetic block which holds said main magnetic pole to form a surface opposed to the magnetic recording medium, and an auxiliary magnetic pole block which supports part of said main magnetic pole and which supports said non-magnetic block; and a magnetic block provided on the side surface of said support block in the direction of track width. The region opposed to the magnetic recording medium is constitued by the main magnetic pole, non-magnetic block and magnetic block.

摘要： A technique for detecting a magnetic recording medium such as a strip on a magnetic card so as to distinguish between a case where a magnetic strip has high coercivity and one where it has low coercivity. A magnetic head detects the existence and appropriate positioning of a magnetic strip which is then fed to a permeability sensor that provides an output signal that is a function of the permeability magnetic strip. A circuit responsive to the output of the permeability sensor provides an output signal indicating the high coercivity strip when the permeability sensor output is low and indicating a low coercivity strip when the permeability sensor output is high.
