We have proposed magnetically induced super resolution (MSR) media consisting of three magnetic layers with in-plane magnetization films (T-MSR). T-MSR realize high MSR performance without readout bias magnetic field. Of two types of T-MSR, exchange-coupled media is suitable for stable readout than magnetostatic-coupled media. The recording density and data transfer rate are estimated to be 3.5 Gbit/inch2 and 6 MByte/se, respectively using a optical head with wavelength of 680nm and numerical aperture of 0.55.
