  • Intermediate layer for antiferromagnetically exchange coupled media
    Patent number: 6811890
    Abstract: The present invention is directed to a disk for information storage. The disk, in one embodiment, comprises a substrate 204, antiferromagnetically exchange coupled first and second ferromagnetic films 220 and 236, a spacer film 228, and at least one buffer film 232 located between the first and second ferromagnetic films. One or more of the following statements is true with respect to the buffer film 232: (i) the buffer film 232 is paramagnetic; (ii) the buffer film 232 is superparamagnetic at temperatures of about 50° C. or less; and (iii) a lattice mismatch between the buffer film 232 and at least one of the first and second ferromagnetic films 220 and 236 in contact with the buffer film is about 5% or less.
