Abstract
A method and system for providing a magnetic recording medium is disclosed. The magnetic recording medium includes a plurality of regions. Each region corresponds to a bit and includes at least one grain. The grain(s) include a plurality of magnetic layers and at least one interlayer between the magnetic layers. The grain(s) have a thickness less than an exchange length of each of the magnetic layers. In addition, at least one of the magnetic layers has a coercivity different from another of the magnetic layers.
