摘要： A bit patterned medium in which an exchange coupling layer induces exchange coupling between adjacent bits in order to reduce a switching field difference resulting from different magnetization directions of bits. The exchange coupling layer is disposed either over or under a recording layer having a plurality of bits. The exchange coupling layer induces exchange coupling between a bit which is to be recorded and an adjacent bit and reduces a switching field difference resulting from a difference between the magnetization direction of the bit to be recorded and the magnetization direction of neighboring bits due to an exchange coupling force generated during the exchange coupling.

摘要： Provided is a bit patterned medium including bridges which induce exchange coupling between adjacent bits in order to reduce a switching field difference resulting from different magnetization directions of bits. The bridges and the bits are integrally formed with each other. The bits are locally connected by the bridges. A magnetostatic force for each bit is reduced due to an exchange coupling between adjacent bits, thereby reducing a switching field distribution of the bits.
