Abstract
The present invention teaches an optical storage disc having a first side having at least one data encoded layer, wherein the at least one data encoded area contains a digital asset in at least one format not readable by all conventional optical disc readers or reader/writers, and a second side having at least one data encoded layer, wherein the at least one data encoded area contains a digital asset in at least one format not readable by all conventional optical disc readers or reader/writers.
Claims20
An optical disc, comprising:
- (a) a first side having at least one data encoded layer, said at least one data encoded area containing a digital asset in at least one format, said at least one format not readable by more than two of a DVD type reader, a DVD type reader/writer, a Divx-DVD type reader, a computer CD type reader, a computer CD type reader/writer, a CD audio player, a CD audio player/recorder, and a CD based game player;
- and
- (b) a second side having at least one data encoded layer, said at least one data encoded area containing a digital asset in at least one format, said at least one format not readable by more than two of a DVD type reader, a DVD type reader/writer, a Divx-DVD type reader, a computer CD type reader, a computer CD type reader/writer, a CD audio player, a CD audio player/recorder, and a CD based game player wherein said first side having at least one data encoded layer and said second side having at least one data encoded layer are in different formats readable by at least two different types of readers wherein the first data format and the second data format are different so as to enable the first data format to be read on a first reader, the first reader being incapable of reading the second data format.
A process for manufacturing a multipurpose optical disc, comprising:
- (a) encoding a first data encodable layer in a first data encoded region on a first side of an optical disc in a first data format;
- and
- (b) encoding a second data encoded region on a second side of the optical disc in a second data format wherein the second data format and the first data format are different so as to enable the first data format to be read on a first reader, the first reader being incapable of reading the second data format.
An optical disc, comprising:
- (a) a first side having a first data encoded region in a first format;
- and
- (b) a second side having a second data encoded region in a second format wherein the first data format and the second data format are different so as to enable the first data format to be read on a first reader, the first reader being incapable of reading the second data format.
