摘要:
An electrodeposited magnetic recording medium having multiple coercivity values is disclosed. In some embodiments, layers having different coercivity levels may be separated by exchange coupled composites and in other embodiments a range of coercivity levels are deposited in a gradient fashion. In some embodiments, the layers with multiple coercivity values comprise bit patterned media islands formed from a photoresist.
