MANUFACTURING METHOD OF MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To manufacture a magnetic recording medium having excellent floating properties and reliability with high yield by suppressing a protrusion on a medium surface by deposition of a big silicon oxide generated when a granular recording layer containing Si and oxygen is film-deposited. SOLUTION: The recording layer is film-deposited by a sputtering method using a target formed by mixing an alloy containing at least Co and a crystalline SiO2powder. COPYRIGHT: (C)2007,JPO&INPIT
