Inventor: FURUKAWA AKIO
IPC: G11B5/56
Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To produce a magnetic disk high in the amplitude of reproducing output all over the surface. SOLUTION: A magnetic layer 8 is deposited on a disk substrate 7 having a desired rugged pattern. While the disk substrate 7 is rotated, an enough large DC current is applied to a magnetic head 11 floating on the substrate to magnetize the projecting part 9 and recessed part 10 of the magnetic layer 8 altogether in one direction. Then a DC current smaller than the first DC current is applied to the magnetic head 11 to invert the magnetization only in the projecting part 9 of the magnetic layer 8. In this process, the DC current applied on the magnetic head 11 and/or rotation of the disk substrate 7 are changed in the radial direction of the disk substrate 7 in such a manner that the magnetic field applied on the magnetic layer 8 is almost uniform in the radial direction of the disk substrate 7.

Filed: 1988-08-23
Abstract: PURPOSE:To prevent suctioned air from being leaked by fixing one end of a seal lip of a bearing to one side of an outer race or an inner race. CONSTITUTION:A shaft 172 of a suction drum 10 is supported through a bearing 20 and a seal lip 34 whose tip is provided with an inner lip and an outer lip is fixed to the bearing 20. The inner lip of the seal lip 34 is in contact with an inner lace 30 thereby offering a seal effect to prevent the invasion of dust or air to the inside of the bearing 20 (around a ball 32). Moreover, the outer lip 38 forms a minute gap with the inner lace 30 thereby ensuring the labyrinth effect.
