Abstract (en)
[origin: EP1047055A1] An optical storage medium comprises cover films, storage layers and a base member which are laminated by means of light transmissive pressure sensitive adhesive layers. An optical storage medium (I), from which information may be read and/or into which information may be recorded with a light beam (6), comprises at least one base member (1) on which the light beam (6) is incident, at least one information storage layer (3) and at least one light transmissive cover film(5). The cover films (5) are bonded to each other, to the surface of the base members (1) and/or to one or more information storage layers (3) by means of one or more light transmissive pressure-sensitive adhesive layers (4). An independent claim is included for a method for the preparation of (I) by providing at least one base member (1) having a surface (2) on which the light beam (6) is incident and comprising a structure of pits bearing an information storage layer (3); laminating a laminate comprising at least one cover film (5), the inner surface of which optionally comprises a structure of pits bearing an information storage layer (3) and a releasable protective film (7) with a laminate comprising at least one pressure-sensitive adhesive layer (4) and a release liner (8) between 2 rollers; removing the release liner (8) to provide a bondable laminate; and laminating the laminate (12) to the surface (2) of the information storage layer (3) on the surface (2) of the base member (1).
