Abstract :
In this paper, we report the feasibility of 100 Mbps data transfer-rate with high reliability and wide-power margin that media can apply to double-deck high density recording of 42 GB capacity corresponding to an optical recording disk system (K. Schep et al, ISOM Tech. Dig., p. 210, 2000) using a blue laser diode at 405 nm, and NA (numerical aperture) of 0.85.
