A description is given of an optical information carrier comprising a substrate (1), a thin reflective layer (5), a dielectric layer (7), a phase-change recording layer on the basis of GeTeSe (9), a dielectric layer (11), an opaque metal reflective layer (13) and a protective layer (15). The information carrier can be inscribed, erased and read by means of a laser-light beam a and, in the inscribed state, complies with the CD-industrial standard. The recording layer (9) comprises an alloy having the composition Ge.sub.x Te.sub.y Se.sub.z, in atom %, wherein47.ltoreq.x.ltoreq.5317.ltoreq.y.ltoreq.4112.ltoreq.z.ltoreq.30andx+y+z.gtoreq.96 and, preferably, equal to 100.
