Abstract

Flexible optical disks (FOD) have a feasibility of their high data-transfer rate and large capacity for archival storage. We have been developing the FOD in order to replace as the media with a current professional video cassette recorder (VCR) of HD-D5 format which have a data-transfer rate of more than 250 Mb/s. Here, we developed the FOD with the high recording sensitivity for high-speed recording, and succeeded to record the 252 Mb/s data with the high-speed tracking control method and optimized write strategy. We also employed the partial response maximum likelihood (PRML) read channel for playback data. We could get and achieve the low byte-error rate (BER) below 2 times 10^-4 at the recording speed of 252 Mb/s, enough to record the video signals of HD-D5 VTR for professional broadcast use.
