Abstract(in English) | High-density recording four times that of a current DVD-RAM has been achieved by applying Domain Wall Displacement Detection (DWDD) technology using a conventional optical head which has the same wavelength of 660 nm and NA of 0.60 as the DVD head. It has been confirmed by using an alternating sampled servo and laser annealing of inter-track area that a recording density of 15 Gbit/inch^2 with a track pitch of 540 nm and bit length of 80 rim has sufficient system margins. A newly developed 1-bit distributed address format has achieved a redundancy of 23 %. These mean that a capacity of 3 GB on a two-inch-diameter disk is now available for mobile use. If applied to a digital video camera, one hour or more of MPEG2 video contents can be recorded at a bit rate of 6 Mbps. |
