MAGNETO-RESISTANCE EFFECT TYPE PLAYBACK HEAD

PURPOSE:To decrease off-track noises by regulating the shape of a shielding layer in such a manner that the magnetic flux from a medium does not intersect with MR elements and electrodes, thereby suppressing the induced electromotive force between the MR elements and the electrodes. CONSTITUTION:The...

Zusammenfassung:	PURPOSE:To decrease off-track noises by regulating the shape of a shielding layer in such a manner that the magnetic flux from a medium does not intersect with MR elements and electrodes, thereby suppressing the induced electromotive force between the MR elements and the electrodes. CONSTITUTION:The sizes a1 and l1, a2 and l2 of magnetic layers 2 and 3 for shielding are regulated like a1
