| Abstract: | The thermal characteristics of magnetic field modulation (MFM) recording are analyzed. It is found that the heat accumulation in MFM recording can greatly reduce the temperature gradient at the recording edge, resulting in a reduction of bit boundary regularity. A specially considered dual modulation method is thus proposed and discussed which shows a greatly improved thermal situation. |
