| Abstract(in English) | In broadcasting stations, the data transferrate of phase change optical disk systems for HDTV must be more than 100 Mbps. A conventional phase change disk system must drive a laser diode with multiple pulses in order to record data. However, this requires a large circuit if the data transfer rate is more than 100 Mbps. So high linear velocity must be needed for high transfer rate. It is expected that same cooling effects as adding multiple pulses appear at high linear velocity. The result of a read/write experiment without multiple pulses that a bit error rate of about 10^<-6> was obtained at 100 Mbps when random data was recorded onto a phase change disk without multiple pulses with using RLL (1,7) code and PRML at a read/write linear velocity of 25 m/s. |
