An optical recording medium has a phase-change recording layer containing Sb
and
Te as essential elements therefor, to which is added at least one element selected
from the group consisting of Ag, Au, Cu, Zn, B, Al, Ga, In, Si, Ge, Sn, Pb, N,
P, Bi, La, Ce, Gd, and Tb, the recording layer being capable of assuming an amorphous
phase changed from a crystalline phase by the application of a laser beam thereto,
thereby optically recording information. Recording marks are formed in the recording
medium by converting a light emission wave of laser beam into a recording pulse
train comprising a plurality of on-pulses and off-pulses, with a recording frequency
being continuously changed corresponding to the location of each of the recording
marks in the radial direction of said recording medium. A recording apparatus has
laser beam driving circuit means, signal generation means, and signal transmission
means for achieving the above recording method.
