An optical disc recording method and apparatus is capable of overwriting a
phase change optical disc at high speed. With a preceding erasing beam
out of two laser beams, a modulation component in an RF signal recorded
on an optical disc is erased to a state where no problem occurs (the
reflectance difference is reduced) and the top level is decreased to 70
to 40% of a top level of an original RF signal. After that, with the
subsequent recording beam, a space is recorded at a laser power at which
top level is reset to the original state (before the erasing process),
and a mark is recorded at a laser power which can sufficiently decrease
the bottom level. Consequently, even when the recording speed is the
quadruple speed (about 1.6 to 2 times of a specification) much higher
than a specific recording speed (for example, 2 to 2.4.times.) of a phase
change optical disc, overwriting can be performed with a recording
characteristic which can satisfy a regenerating characteristic
specification.
