Information carrier, method for producing same

Information carrier, comprising at least two solid material interfaces at which information is or may be applied and whereat the information is stored by local modulation of at least one solid material characteristic, from which characteristic reflection of electromagnetic radiation depends at said interfaces, further comprising at least one intermediate layer between said two solid material interfaces, which layer transmitting said radiation, said information being readable from at least one of said solid material interfaces by means of radiation of predetermined wavelength, wherein said intermediate layer comprises a dielectric layer system with at least one layer, said layer system having an optical thickness which, at least in a first approximation, is m.multidot..lambda..sub.o /4, wherein m is integer, at least unity and is uneven and wherein .lambda..sub.o designates the wavelength of said radiation which is transmitted through said at least one dielectric layer of said dielectric layer system, wherein, departing from said m being integer, m may be reduced by an amount of up to 0.6 or increased by an amount of up to 0.2.
