VERTICAL MAGNETIC RECORDING MEDIUM, METHOD FOR MANUFACTURING VERTICAL MAGNETIC RECORDING MEDIUM, AND MAGNETIC RECORDING/REPRODUCING DEVICE

摘要

A vertical magnetic recording medium includes at least a lining layer, a seed layer, an intermediate layer and a vertical magnetic recording layer in this order on a nonmagnetic substrate. The seed layer is an hcp-structured (002) crystalline orientation layer, and the intermediate layer includes a first intermediate layer composed of a bcc-structured (110) crystalline orientation layer and a second intermediate layer composed of an hcp-structured (002) crystalline orientation layer in this order. The bcc-structured (110) crystalline orientation layer is preferably a structure containing a Cr of 60 atm% or more. The magnetic recording medium makes it possible to record/reproduce high-density information by achieving separation of crystal grains, a fine crystal grain diameter and vertical orientation of the vertical magnetic recording layer at the same time.
