Abstract :
The relation between recording mark formation and jitter value with radial orient spot (ROS) type laser spot recording was investigated by using a new imaging method of conductive-atomic force microscopy (C-AFM). The readout performances of recording marks were studied by changing the terminal resistance of optical pickup head and writing strategies. The results of clear C-AFM images showed that is possible to adjust the conditions of terminal resistance and writing strategies to have better readout signal performance.
