Title: Production of vertical magnetic recording medium
Inventor: YANAGISAWA GEN
IPC: G11B5/858
Filed: 1985-07-23
Abstract: PURPOSE:To simply obtain a vertical magnetic recording medium having satisfactory adhesion to its support and high durability and sliding smoothly along a magnetic head by adhering an anodic oxide film contg. a magnetic material filled into the pores in the film up to the middle positions to a flexible support and by using the anodic oxide film as a vertically magnetizable recording layer. CONSTITUTION:A thin metallic plate 1 of Al or an Al alloy is anodically oxidized to form an anodic oxide film 2 having many pores 3. A magnetic material 4 is filled into the pores in the film 2 up to the middle positions and the plate 1 is adhered to a flexible support 7. The plate 1 is then removed so as to leave only the anodic oxide film 2. Since the magnetic material is filled into the pores in the anodic oxide film up to the middle positions, a vertically magnetizable layer having favorable shape anisotropy is formed. An adhesive 6 enters the remaining parts of the pores, so the adhesion of the vertically magnetizable layer to the support is remarkably increased.

Abstract: PURPOSE:To simplify a testing method and to easily execute the test by using a twisting drill for a drill workability test after a suction roll is molded out of ferrite-austenite two-phase stainless steel. CONSTITUTION:The twisting drill formed of high-speed steel is used to bore plural through holes or holes which are each closed at one end in a roll shell after molding or a test-piece made of the same material with the roll shell, and thus the boring workability of the roll shell is evaluated from whether or not holes which are deeper than specific depth can be bored with one twisting drill.
