Abstract

This study aims at achieving a high speed optical disk drive for multimedia storage used in network systems. The feasibility of our target has been confirmed by the following results and techniques. High speedparallel data transfer at 336 Mbit/s in 2/7 run length limited (RLL) code or 300 Mbit/s in 1/7 RLL code has been achieved experimentally with eight beams. Focus offset has been reduced by a multibeam laser diode fabricated in junction down structure and a wide-angle lens system. Tracking error is reduced by nearly 6 Db compared with that of a conventional method. This was achieved by suppressing the mechanical interaction between the lens actuator and the beam rotation prism. The crosstalk canceler reduces both intercircuit crosstalk and optical crosstalk with pseudo crosstalk generated by a circuit. It reduces the worst-case intercircuit crosstalk by more than 14 Db.
