Title: Production of magnetic recording medium
Inventor: YAMAGUCHI KIYOTO
IPC: G11B5/84
Filed: 1986-08-08
Abstract: PURPOSE:To obviate the generation of magnetic anisotropy in a surface direction even if the film thickness of an underlying layer is increased by subjecting the surface of a nonmagnetic substrate layer to texture finishing to provide many polishing traces in the circumferential direction thereto, then forming the underlying layer consisting of a nonmagnetic metal. CONSTITUTION:The substrate is subjected to the texture finishing by tape polishing before the Cr underlying layer and magnetic layer are continuously sputtered. The tape polishing is executed by disposing a tape 14 fixed with the fine abrasive materials on an Ni-P layer 2a provided on the substrate 1b and rotating and moving the substrate 1b and the tape 14 respectively in arrow directions while pressurizing a contact part 16 formed by bending the tape 14. The many concentrical polishing traces are produced on the surface of the Ni-P layer 2a on the substrate 1b by such polishing. The Cr underlying layer and the Co magnetic layer are continuously formed by sputtering on the Ni-P layer. The generation of the intra-surface magnetic anisotropy with an increase in the thickness of the Cr underlying layer is decreased.
