Document Type and Number:
Japanese Patent JP3326549
Kind Code:
B2
Abstract:
A magnetic head assembly 1E is constituted in such a manner as a pair of magnetic head mechanisms 3E, 3E, which are formed by accommodating a magnetic head 5 in a shield ring, respectively, are disposed opposite by opposing the proximal end rail 15a and the distal end rail 15b of one magnetic head mechanism 3E to the distal end rail 15b and the proximal end rail 15a of the other magnetic head mechanism 3E, respectively. A pair of shield rings 6,6 are positioned symmetrically with respect to each other (not in off-set). A spacing Ls of a pair of shield rings is shorter than a spacing Lc between the one shield ring 6 and the other magnetic head core 8. The outer magnetic flux phi flows to each other shield ring 6, so that the flux phi c which flows to the magnetic head core 8 reduces. Thus, the induced voltage in the coil generated by any outer magnetic field is controlled to reduce noise.
