Abstract
PURPOSE: To form the magnetic head suitable for reading of high density recording with accuracy and ease by combining two sets of magnetoresistance elements provided with plural magnetic resistance paths which become zigzag form current paths and a bias magnet.
CONSTITUTION: Plural magnetoresistance paths 6 constituting magnetoresistance elements 5 are disposed zigzag in correspondence to the respective phases of magnetic gratings 4 to increase the detection sensitivity of magnetic scale 1 signal and reduce the pitch of the magnetic gratings 4. Magnetic path members 7 composed of high magnetic thin-films are disposed for the respective magnetoresistance paths 6 to form closed magnetic paths with the respective magnetic gratings 4. The magnetoresistance elements 8, 9 placed in sufficient saturated magnetic fields and a bias magnet 10 are so combined as to guide the leakage magnetic fluxes from the respective magnetic gratings 4. Output terminals 15, 16 are connected at the intermediate connection points of the magnetoresistance paths 6, 6
