Title: Magnetic recording medium
Inventor: AOYAMA AKIRA
IPC: G11B5/73
Filed: 1989-05-19
Abstract: PURPOSE:To obtain the magnetic recording medium having a high coercive force and high S/N by constituting a magnetic film of Co-Cr-Ti and specifying the amt. of the Ti to be added to a specific value or below. CONSTITUTION:The magnetic film is constituted of the Co-Cr-Ti and the amt. of the Ti to be added is specified to <=8atm.%. Hc increases largely and Br.delta decreases gradually with the amt. of the Ti to be added simply when the small amt. of the Ti is added. However, S/N is inferior to the S/N of the film which is not added with the Ti if the Ti is added at the ratio higher than 8at.%. Such tendency occurs in the decrease in signals by the gradual decrease of Br.delta, from which the preferable amt. of the Ti to be added is <=8at.%. The magnetic recording medium having the high coercive force and high S/N is obtd. in this way.
