Abstract
Bit-by-bit detection is achieved at a recording density of 0.11 μm pits on a super-RENS disk with a platinum oxide layer. Pits and spaces are arranged as a recording pattern for pit position recording. After recording by laser pulses with pre- and post-heating, the pattern is correctly reproduced despite the size smaller than the resolution limit. Furthermore, the pattern is clearly binarized by a read channel circuit for bit-by-bit detection.
