Influences of yaw-angle on read/write characteristics investigated by computer simulation

A computer study of recording loss due to a yaw-angle (skew) is discussed. Use of yaw-angle when writing on a medium enhances non-linear distortion in the recorded magnetization on the track center as well as on the track edges, resulting in the reduction in signal output. The degree of the reduction is strongly influenced by the magnetic properties of the recording medium and writing conditions (write head gap-length, spacing between head and medium, etc.). An isotropic medium and narrow spacing recording with a narrow gap head is preferable for reducing the yaw-angle loss
