摘要：
A method for manufacturing a magnetic recording medium including a nonmagnetic substrate, an intermediate layer over the nonmagnetic substrate, and a granular magnetic layer for recording information, disposed on the intermediate layer. The method includes sputtering a Co alloy, a Ti oxide, a Si oxide and a Co oxide simultaneously to form the granular magnetic layer containing Co alloy magnetic particles and an oxide magnetically separating the magnetic particles.
