Abstract
A discontinuous flash chrome interlayer of about 5 to 25 .ANG. is incorporated between the upper and lower magnetic recording alloy layers. This flash non-magnetic separation layer is so thin that it is, in fact, a discontinuous layer, so that while the benefits of having some chrome flashed on the surface of the first portion of the magnetic recording alloy are achieved, yet the upper and lower magnetic recording alloy layers are not completely physically separated as they are in disks made according to known sputtering processes.
