Abstract

The present invention relates to an optical storage medium (10) comprising a substrate layer (12) having a pit structure (14, 16) storing optical data, and a groove structure (18, 20) for storing optical data by projecting a laser light beam (22) thereon; and a recording layer stack (24) deposited above the substrate layer(12), comprising a first dielectric layer (26), a first recording layer (28), a second recording layer (30), and a second dielectric layer (32), wherein no metal layer is provided between the recording layer stack (24) and the substrate layer (12), or an aluminum layer (34) having a thickness of between 5nm and 30nm is deposited between the recording layer stack (24) and the substrate layer (12). The present invention further relates to stamper (44) for structuring an optical storage medium (10) according to the invention and to a method of producing an optical storage medium according to the invention.
