Abstract

PURPOSE: To improve detection sensitivity by arranging two lead wire fitting parts outside a rotary magnetic body by folding a magnetic resistance element and then by placing the detection part of the magnetic resistance element closely to the rotary magnetic body.
CONSTITUTION: When the recording wavelength signal on recording medium 1 is a digital signal of constant wavelength λ, magnetic resistance element 2 is folded at nλ n is an integer it in a channel shape and lead wire fitting parts R1 and R2 of it can be arranged outside of medium 1. This can be realized in case of a digital signal, and consequently element 2 can be set close to medium 1 without paying attention to the thickness of solder at lead wire fitting parts R1 and R2, so that the detection sensitivity can be improved.
