OPTICAL MEDIA IDENTIFICATIONS
Methods, systems, and apparatus, including computer program products for identifying optical disc media. In one aspect a method is provided that includes receiving printed information read from an optical media disc. Identifying a media-type of the optical media disc from the printed information. The printed information can be printed on optical media disc in ink. The printed information can be printed on optical media disc which includes a plurality of stripes. The printed information can be read from a burst-cutting area on the media disc
1 . A method comprising:
receiving printed information read from an optical media disc; and
identifying a media-type of the optical media disc from the printed information.
2 . The method of claim 1 , where:
the printed information is printed on optical media disc in ink.
3 . The method of claim 1 , where:
the printed information is printed on optical media disc which includes a plurality of stripes.
4 . The method of claim 1 further comprising:
reading the printed information from a burst-cutting area on the media disc.
5 . The method of claim 1 , further comprising:
reading the printed information using a pick-up head and adjusting the pick-up-head to read data from the optical media disc based on the media-type of the optical media disc.
6 . The method of claim 1 , further comprising:
reading data from the optical media disc based on the identified media-type.
7 . The method of claim 1 , where identifying a media-type of the optical media disc includes:
decoding information based on a disc identification code structure.
8 . The method of claim 1 , where the disc identification code structure includes:
information identifying a media format, a number of media layers and a media-sub-format.
9 . The method of claim 8 , where:
the media format can include one of: CD, DVD, HDDVD or BD.
10 . The method of claim 8 , where disc identification code structures includes:
parity information.
11 . A method comprising:
receiving a media-type for an optical media disc; and
printing information encoding the media-type onto the optical media disc.
12 . The method of claim 11 , where:
the information is printed in an area incident with a burst-cutting area.
13 . The method of claim 11 , where printing information includes:
printing a series of stripes encoding the media-type.
14 . The method of claim 11 , where printing the media-type information includes:
printing information based on a disc identification code structure.
15 . The method of claim 14 where:
the disc identification code structure includes information about: media format, media layers and media sub-format.
16 . The method of claim 15 , where:
media format includes one of: CD, DVD, HDDVD or BD.
17 . An optical media including:
a printed code identifying the media type of the optical media.
18 . The media of claim 17 where:
the printed code is printed in ink.
19 . The media of claim 18 , where:
the ink is low-reflectance ink.
20 . The media of claim 17 where:
the printed code is a series of stripes encoding the media-type.
21 . A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:
receiving printed information read from an optical media disc; and
identifying a media-type of the optical media disc from the printed information.
22 . A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:
receiving a media-type for an optical media disc; and
printing information encoding the media-type onto the optical media disc.
23 . A system comprising:
receiving printed information read from an optical media disc; and
identifying a media-type of the optical media disc from the printed information.
24 . A system comprising:
receiving a media-type for an optical media disc; and
printing information encoding the media-type onto the optical media disc.
