A rewritable dual-layer phase-change optical disk with a balanced transmittance structure for the layer located at the laser beam incident side (Layer 0) was developed. In this disk structure, transmittance of Layer 0 is almost constant, whether the layer is recorded or not. This structure was realized by adopting Ge-Sb-Te film that has appropriate optical constants, and optimizing the thickness of the dielectric layers. It is proved that this disk structure is effective in suppressing the influence of the recording state of Layer 0 on the layer beneath (Layer 1). Practical performances of the disk with this structure were confirmed for both layers. The feasibility of up to 55 GB capacity was examined for this rewritable dual-layer phase-change optical disk.

“…The recorded signal is the "D8-15", RLL(2,10), modulation code. 2) The LD is modulated by RF current for the suppression of mode-hopping noise during read-back. A chromatic corrector is inserted into the optical path to compensate chromatic aberration of the objective lens.…”

For an optical disk system using an objective lens of numerical aperture (NA) 0.7 and a GaN laser, the performances of the groove-recording scheme were investigated. A disk having 17 GB capacity showed the initial jitter of 11.9% with an equalizer for digital versatile disks (DVD). With an adaptive equalizer and a Viterbi decoder, sufficiently low bit error rates and wide tilt margins were obtained.
