Abstract
PURPOSE: To increase the accuracy of the spacing between magnetoresistance effect elements and enhance the accuracy of detection by detecting the information of a magnetic recording medium by the use of the magnetoresistance effect elements formed on a substrate by means such as vapor deposition and photoetching.
CONSTITUTION: Magnetic information has been recorded in the form of N and S on a magnetic recording medium 2 along its rotating direction. A magnetoresistance detecting body 6 is disposed by way of a micro-spacing to this magnetic recording medium 2. The magnetoresistance detecting body 6 is formed thinly on the surface of one platelike substrate 5 having electrical insulation characteristic by means such as vapor deposition or photoetching. Magnetoresistance effect bodies 4 are formed by input terminals (A), (C), detecting terminals (B), (D), resistance parts R11WR42 and connecting parts (a)W(d).
