Abstract
PURPOSE: To make broad the permissible range of spacing and to increase the reliability, by locating strip shape MR elements having different width in parallel lengthwise and in the interval of nP and connecting them in series, in the magnetic field detection element for magnetic field detection of magnetic medium where the magnetic signal is recorded in the form of bit length P of equal interval.
CONSTITUTION: The two strip-shape elements 12, 13 different in the widths W1, W2 of the same thickness are formed on the board 11 with the conductor terminals 14, 15 in parallel in the interval of nP (where; n is an 1 or more integer, and P is the bit length). In this case, W1 is greater than W2. One of two MR elements 12, 13 is connected to the current supply source and another is to the output terminal 17 via the conductor terminal 14. This magnetic detecting element 10 is located on the magnetic recording medium 3 of magnetizing 2 having the bit length P of equal interval for the magnetic signal via the spacing of D. Since the output is the sum of two MR type elements 12, 13, no saturation characteristics are caused. A plurality of MR elements pairs can be used. Thus, the range of spacing is made broad and the reliability can be increased.
