Problems solved by technology

Needless to say, the benefit to the user is necessarily to the detriment of the film producer: since he only gets paid once
[0008] The Fourth Way is also released on DVD, but now this DVD is "restricted play"
After this, the DVD cannot be used

Embodiment Construction

[0026] Hereinafter, the present invention will be explained for the case of DVD. It will be clear to those skilled in the art that certain details will have to be changed in the case of discs of different formats.

[0027] figure 1 A cross-sectional view of a part of an optical disc 10 with a rotation axis 11 and a central hole 12 is schematically shown. The disc 10 is made of optically transparent material, it is known that the disc comprises at least one storage layer 13 containing a pattern which can be read by an optical pickup 3 which emits a laser beam 4 and receives the reflected laser light 5. The laser beam 4 is irradiated on the disc 10 at one main surface 14, referred to as the optical surface. Optical discs may include two or more storage layers that can be read from the same side. It is also possible for an optical disc to include two storage layers that can be read from opposite sides; in this case, both disc surfaces are optical surfaces. In the present exa...

Abstract

An optical disc (10) comprises at least one storage layer (13) with at least one portion of content being a movie and at least one other portion of content being an advertisement. Initially, the advertisement is visible, but after some time the advertisement is no longer visible. The optical disc may be provided with a label (16) containing an advertisement image (43) which initially is visible but after some time is no longer visible. The optical disc may be accommodated in a storage box (100) provided with an advertisement image (143) which initially is visible but after some time is no longer visible.

Description

technical field [0001] This invention relates generally to the field of optical discs and their storage cases, particularly but not exclusively DVDs. Background technique [0002] As is known, optical storage discs comprise at least one track in a storage space in which information can be stored in the form of a data pattern, either in the form of a continuous spiral or in the form of a plurality of concentric circles. Information is typically read from the disc by spinning the disc and scanning the tracks with a light beam, typically a laser beam. Since optical disc technology in general, ie the way in which information is stored in an optical disc and the way in which optical data is read from an optical disc, is well known to those skilled in the art, a more detailed description is not necessary here. This applies to the physical construction of the disc as well as the format used to store the information. [0003] The invention is particularly useful in the field of DV...
