Title: Production of perpendicular magnetic recording disk medium
Inventor: ISHIBASHI KAZUO
IPC: G11B5/852
Filed: 1989-12-27
Abstract: PURPOSE:To form soft magnetic layers having the axis of easy magnetization oriented in the radial direction on both sides of a disk substrate at one time by forming the soft magnetic layers while applying an alternating magnetic field perpendicular to the disk substrate to generate concentrical eddy currents therein, and then forming a perpendicular magnetization layer on this soft magnetic layer. CONSTITUTION:An alternating magnetic field 21 having uniform intensity or showing concentrical variation of intensity from the center of a disk substrate 11 is applied perpendicularly to the disk substrate 11 which has electric conductivity, so that concentrical eddy currents 22 are caused in the disk substrate by electromagnetic induction. These eddy currents 22 generate a radial magnetic field 23 from the center on the disk substrate, by which the axis of easy magnetization of the soft magnetic layer is oriented while the axis of difficult magnetization is oriented in the tracking direction. The alternating magnetic field 21 to be applied is produced by a coil, and this coil can be easily removed when the perpendicular magnetization film is formed. Thereby, soft magnetic layers having the axis of easy magnetization in the radial direction can be obtained.

Patent JP-H07167774-A (JP)
Title: Polarization analyzer
Inventor: NAKAMURA HIDEKI
IPC: G01J4/04
Filed: 1993-12-15
Abstract: PURPOSE:To arrange incident light flux and reflection light flux on the same axis, miniaturize the device and make measurement efficient by slantingly inserting a translucent mirror on an optical axis vertical to a specimen surface and focusing linear polarized light from a light source arranged in the perpendicular direction to the optical axis on the specimen surface through a lens. CONSTITUTION:Laser light of linear polarized light from a parallel flux light source G is reflected at a translucent mirror H and focused on a point O on a specimen surface S with a large opening lens L. The reflection light from the specimen S reflects with the same divergent angle alpha as the focusing angle alpha, becomes parallel flux at the lens L, transmits in the translucent mirror H, goes through a photoprobe P into a light reception element D having position resolution and falls on a CCD cell D as a circular spot. The illuminance in the spot is not uniform and polarization characteristics for different incident angles to the specimen are obtained by turning the photoprobe P. As the incident light flux and the reflection light flux are on the same axis, a driver to change the incident angle is not necessary and the device can be small-sized. Also, as various incident angles are simultaneously measured, efficiency is improved.
