摘要： PROBLEM TO BE SOLVED: To achieve a high recording density by narrowing a recording track width to enable a high track density while maintaining recording density.
SOLUTION: The composite magnetic head is provided with a recording head portion basically constituted of a first magnetic layer forming a trailing part during recording in a magnetic storage medium, a second magnetic layer forming a leading part during recording in the magnetic storage medium, and a gap set between the first and second magnetic layers to generate a leakage magnetic flux, and a magneto-resistance effect reproducing head portion for generating a resistance change corresponding to a magnetization pattern recorded on the magnetic storage medium by the recording head portion. There are an overlapped portion between the first and second magnetic layers 21 and 22 with parts disposed in the gap. Additionally, in the composite magnetic head, the overlapped portion of the second magnetic layer forms a projected shape with respect to a part other than the overlapped portion.

摘要： PROBLEM TO BE SOLVED: To prevent damage to a medium caused by change in the posture of a head in loading and also prevent accumulation of depositions, in a loading/ unloading type magnetic disk device. SOLUTION: In the substrate 101, 201 for the manufacture of a magnetic disk, which is mounted in a loading/unloading type magnetic disk device; protrusions 102, 203 are arranged and formed in accordance with the loading position of a magnetic head in the outer peripheries of the substrate 101, 201; the projections block the magnetic head when it comes into contact with the data recording surface of the magnetic disk by changing the posture and entering at a height below the designed level in the loading at the loading position; and the protrusions also remove stains stuck to the flying surface of the head. With the purpose of reducing the contact area in the blocking by the protrusions 102, 203, the protrusions 102, 203 are given distribution in height. As a method of forming the protrusions 102, 203 with the height distribution, a laser output/focal position are controlled in a laser beam machining.

摘要： PURPOSE:To eliminate the Barkhousen noises and base line shift by altering a reading current to a magneto resistance effect type (MR) head magnetic film to perform a retrial when read errors are not restored by a repeating retrial. CONSTITUTION:When read errors occur with the reproduction of record information of a magnetic disc 1 by a compound head 3 of the MR head, a repeating retrial is performed through an offsetting function 62 and a retrial function 63 of a disc controller 6. Then, when the read errors are not restored after a specified number of retrials, a reading current to be applied to the MR film of the head 3 is altered by a reading current control function 61 of the controller 6 and the same repeating trial is performed. This achieves an elimination of the Barkhousen noises and base line shift of the MR head thereby preventing the generation of the lead errors.
