<p>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 and, in the inscribed state, complies with the CD-industrial standard. The recording layer (9) comprises an alloy having the composition GexTeySez, in atom %, wherein 47 « x « 53, 17 « y « 41, 12 « z « 30, and x + y + z » 96 and, preferably, equal to 100.</p> |
