Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To regularly provide a luminous flux having no polarization of polariz ing component by providing a prism formed of an optically active material, so that the luminous flux causes a. difference in transmitting optical path length of each beam transmitted by the prism. SOLUTION: A first triangular prism 2 formed of an optically active material and a second triangular prism 3 formed of an optically non-polarizable and inactive material having a refractive index substantially equal to it are bonded together in the inclined surfaces to constitute a cubic prism. The incident luminous flux is emitted with the plane of polarization being rotated by the optical activity of the first triangular prism 2, but planes of polarization rotated in various directions are included in the emitted luminous flux since the transmitting optical path lengths are differed. The luminous flux is passed through the second triangular prism 3 while holding the plane of polarization at a point of time when it is emitted from the first triangular prism 2.  The inclination ϕof the triangular prisms 2, 3 is selected, or the effective diameter (d) of the incident luminous flux is regulated, whereby a luminous flux having no polarization of polarizing component can be provided.

Title: Production of magnetic recording medium
Inventor: SATO TAKANORI
IPC: G11B5/84
Filed: 1988-09-26
Abstract: PURPOSE:To obtain the magnetic recording medium which is excellent in durability and head contact characteristics by specifying the oxygen introducing rate/ vapor deposition rate at the time of formation of a Co-O film to >=2.0SCCM/(Angstrom / sec). CONSTITUTION:A Co-Cr film is formed as a magnetic layer on a nonmagnetic base and the Co-O film is formed as a protective film thereon. The Co-O film is formed as a vapor deposited Co oxide film by forming high-purity Co into vapor flow for vapor deposition and depositing this vapor on the Co-Cr film while introducing oxygen thereto. The rate of the oxygen to be introduced at the time of the vapor deposition of the Co-O film/the vapor deposition rate is required to be specified to >=2.0SCCM/(Angstrom /sec). For example, there is the possibility that the durability of the protective Co-O film formed by the vapor deposition is insufficient if the oxygen introducing rate/the vapor deposition rate is below 2.0SCCM/(Angstrom /sec). Although the upper limit is not particularly limited, the durability tends to saturate if the oxygen introducing rate/the vapor deposition rate is larger than 7.5SCCM/(Angstrom /sec), and therefore the value below the same is preferable. The durability and the head contact characteristics are improved in this way.
