Dulimarta) Distribution: usa Organization: Michigan State University, Computer Science Department Lines: 10 Hi folks, I talked to a friend of mine about this drive controller but he didn't know exactly how this controller works. Could anybody explain about this controller (RLL). What is the difference between this controller and FM, MFM, M2FM ? Is there any other controlling method besides these ones ? I appreciate your reply. Hans.
