Title: Magnetic disk device
Inventor: AIKAWA SHINICHI
IPC: G11B5/09
Filed: 1988-02-22
Abstract: PURPOSE:To obtain a satisfactory recording/reproducing characteristic in respective high and low density recording/reproducing modes by causing a gap length to be 0.60-1.20 fold minimum magnetic flux inverting interval due to a recording/reproducing signal and providing a cosine-shaped equalizing circuit in a reproducing circuit, to which the reproducing signal is supplied. CONSTITUTION:Since a gap length g0 of a magnetic reproducing head 5, which has cores 6 and 7, is set to the 0.60-1.20 fold minimum magnetic flux inverting interval, a magnetic substance layer 9 of a magnetic disk for low density recording/reproducing disk can be magnetized to a deep part d0 and thus, an over-write characteristic and a reproducing margin at the time of a low density mode can be secured in an enough satisfactory condition. By causing the gap length g0 to be large, there is danger that resolution is lowered and a peak shift is generated. However, by providing a cosine-shaped equalizing circuit 11 in a reproduction processing circuit, the peakshift and the lowering of the resolution, which goes to be a problem, can be prevented in a high density mode.

Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To improve abrasion resistance while making the most of tenacity of a coating film mainly composed of Cr2N by including a specific quantity of boron in an ion plating film mainly composed of Cr2N, and forming a Cr2N  111} surface as main orientation. SOLUTION: A chrome boron alloy is used as a target of an ion plating method, a chrome nitride coating film containing boron in an outer peripheral sliding surface of a sliding member is formed in a nitrogen atmosphere, and in chrome nitride of the coating film mainly composed of Cr2N, main orientation is set as a Cr2N  111} surface. The boron content of the coating film is adjusted to a range of about 0.05 to 20 wt.% by the composition of a chrome boron alloy. A reason for limiting this range is that abrasion resistance of the coating film is not improved when the boron content of the coating film is less than about 0.05% and the abrasion resistance of the coating film fairly reduces to the contrary when the boron content exceeds about 20%.
