ABSTRACT:
A magnetoresistive playback head for a small magnetic disk. Electrodes connected to an MR element each has a linear portion extending over a length which is more than ten times greater than the width of the MR element. The electrodes each extends from the MR element at an angle less than 14 degrees. This allows only a single magnetic domain to exist in the MR element and frees the magneto-resistive response from distortions or hysteresis. As a result, signals reproduced from a magnetic recording medium do not include any distortion or noise.
