Title: Magnetic recording medium
Inventor: FUJII SHIGEO
IPC: G11B5/64
Filed: 1990-03-29
Abstract: PURPOSE:To decrease noise and to improve high recording density characteristics by using a Co-Cr-Ta thin film as a magnetic layer and alternately depositing Co nonmagnetic layers and Co-Cr-Ta magnetic thin films to form a multilayer film. CONSTITUTION:On a nonmagnetic substrate, there are successively formed a base layer comprising a Cr thin film and a Co-Cr-Ta thin film magnetic layer, and further, Co nonmagnetic thin film layers and Co-Cr-Ta magnetic thin films are alternately and continuously deposited thereon. Thereby, interactions of the magnetic layers can be controlled not only in the intrasurface direction but in the depth direction. Since crystal grains in the Co-Cr-Ta thin film easily have segregation of Cr on the grain boundaries, and the multilayer structure consists of these magnetic layers interposing nonmagnetic intermediate layers, a magnetic wall between adjacent bits can be significantly made narrow. Thereby, the obtd. medium has low noise and improved high recording density characteristics.

When a refractive index (n) of the transparent substance of the hemisphere 1 against air is selected as n=(r+R)/r, an incident light beam passing through the center O in the optional direction of A passes through B and O, is reflected by C, returns again through O and B, but parallel rays A'B' which are separated by (e) which is smaller enough than R and (r) are refracted at B', reach C, where it is  reflected, and refracted once again, and become B''A'' which is parallel with BA. A light beam in the directin of A'' returns in the direction of A' in the same way. That is to say, a parallel luminous flux having width of 2e is reflected as it remains a ?luminous flux having almost 2e. In this way, a line of collimation of transit can be set easily by ?using this reflector together with a laser transit.
