Paper Abstract
The pit shape in magnetic field modulation recording is obtained from temperature profile which is calculated by using three dimensional thermal diffusion equations considering the movement of laser spot. The pit edge shape changes more elliptically with increasing disk velocity. The calculated frequency response does not degrade so much as the pit edge shape changes. The influence of disk velocity to the frequency response is less than that of recorded pit duty. These calculation method is useful for obtaining the recording characteristics of read-write channel, when various parameters are changed, without experiments.
