This paper describes servo technology for the improvement of data transfer rate and access time in a high-speed optical disk drive. First, read-write characteristics of the continuous composite servo format and the sampled servo format are discussed in terms of the recording power conditions needed to achieve a stable data read-out. Next, An optical head with the laser diode and optics separated from the positioner carriage is presented. The separated optical head's tracking servo stability and spot collimating performance are discussed. Finally, a new two-dimensional rotary lens actuator with a high resonant frequency is proposed.
