摘要： A magnetic disk having a lubricating film that covers a data region and a CSS region formed on the surface thereof. The lubricating film secures low tackiness and low sliding friction in the data region, and secures CSS durability in the CSS region. Since the problem of lubrication between the magnetic disk and a magnetic head can be avoided either in normal operation or in the event of an abrupt stop of the disk drive, high reliability can be secured. The present invention provides also a magnetic recording/reproduction apparatus using the disk. Because the lubricating film formed in the data region of the magnetic disk is firmly fixed to the surface of the magnetic disk, it hardly invites adhesion and has a sufficient film thickness for securing durability under sliding friction. The lubricating film in the CSS region comprises both a lubricant having high fixing force and a lubricant having low fixing force to the surface of the magnetic disk, it has high CSS durability. It is therefore possible to obtain a high-reliability magnetic disk and a high-reliability magnetic recording/reproduction apparatus.
