Recording results and coding considerations for the resonant bias coil overwrite technique
Abstract
Magneto-optic direct overwrite using the resonant bias coil technique has been demonstrated for field frequencies as high as 12 MHz. The technique is compatible with multi-channel recording and allows larger coil-to-media spacing than obtained using conventional field modulation techniques. Suitable run length limited codes are investigated which satisfy an even consecutive zero constraint. The performance of these codes appears to be competitive with the performance of more traditional (d,k) codes. © 1989, SPIE.
