MAGNETIC RECORDING MEDIUM AND MAGNETIC STORAGE DEVICE USING THE MEDIUM

WIPO Patent Application WO/1998/006093

A1

A magnetic storage device provided with a magnetic recording medium having a magnetic layer formed on a single or plural base layers, a driving section which drives the medium in the recording direction, a magnetic head including a recording section and a reproducing section, means which moves the magnetic head relatively to the medium, and recording and reproducing signal processing means which inputs signals to the head and reproduces signals outputted form the head. The reproducing section of the magnetic head is a magnetoresistance effect magnetic head. The single base layer or one of the base layers of the recording medium is made of an alloy material composed mainly of at least one element selected from among a first group of Cr, Mo, V and Ta and at least one element selected from among a second group of B, C, P, and Bi. Thus, a highly reliable magnetic storage device which records information at a high density and reproduces it is obtained.
