Title: High-density recording and reproducing head and high track density magnetic recording and reproducing device
Inventor: MIYAMOTO NORIFUMI
IPC: G11B5/31
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To make a curve of a magnetization transition region recorded on a medium small by using a high saturation flux density material for an upper magnetic pole material, and selecting a higher saturation flux density than that of a lower magnetic pole. SOLUTION: An upper shield film 13 serves also as a lower magnetic pole of a recording head, and this lower magnetic pole 13 is projecting in the direction of the upper magnetic pole, and the upper width Wg2 of this projection decides a recording gap width. A recording gap 15 is formed on the lower magnetic pole 13, and the upper magnetic pole 14 is arranged thereon. For this upper magnetic pole material, a material with a higher saturation flux density than that of a lower magnetic pole is selected. A geometric width Wg1 of the upper magnetic pole 14 is made to be at least 1.5-2 times as long as the recording gap length on one side than the projection width Wg2 of the lower magnetic pole 13.  In such a manner, information is recorded by using a recording magnetic field leaking to the medium counter face side from the recording gap 15 constituted by the upper magnetic pole 14 and the lower magnetic pole 13.
