Definitions

  • the present invention relates to an information storage medium and a method of recording and/or reproducing data thereon, and more particularly, to an information storage medium in which information about a user data area is recorded on an inside and/or outside of a basic recording unit of the user data area, and a method of recording and/or reproducing data on the information storage medium.
  • optical disks are widely used as information storage media for optical pickup apparatuses to record/reproduce information in a non-contact manner.
  • Optical disks include compact disks (CDs) or digital versatile disks (DVDs) according to their information storage capacity.
  • Examples of recordable optical disks are a 650MB CD-R, a CD-RW, and a 4.7GB DVD+RW.
  • HD-DVDs having a recording capacity of 20GB or more are under development.

  • the number of sector addresses increases from the inner boundary Rj n to the outer boundary R out -
  • the user data area A includes a plurality of error correction code (ECC) blocks.
  • ECC error correction code
  • FIG. 2 illustrates that information about the address of each ECC block is recorded as a groove wobble in a recordable optical disk because data may be randomly recorded or reproduced regardless of the sequence of physical addresses of basic recording units.
  • information about a user data area is recorded as a groove wobble.
  • the recordable optical disk has a layer and does not include layer information. It is difficult to keep consistency between the formats of the recordable optical disk and reproduction-only optical disks.

  • SA sector address
  • reproduction-only optical disks In contrast to recordable optical disks, reproduction-only optical disks have no grooves in a user data area, which makes it necessary to record information about the user data area in a different way than in recordable optical disks.
  • Recordable optical disks and reproduction-only optical disks have been developed so as to have greater recording capacities.
  • Recording capacity can be increased by shortening the wavelength of a recording optical source or by increasing the numerical aperture of an objective lens.
  • recording capacity can also be increased by having a plurality of storage layers.

  • the first and second information storage layers l_ ⁇ and L 2 have lead-in areas 1a and 2a, respectively, and lead-out areas 1 b and 2b, respectively.
  • sector address numbers (X) increase from an inner boundary R in to an outer boundary Ro ut -
  • sector address numbers (X') increase from the outer boundary R ou t to the inner boundary

  • Recordable optical disks also store various conditions of recording. Hence, a user data can only be properly recorded on or reproduced from an optical disk by reading information from the lead-in areas and the lead-out areas.
  • information storage media having a plurality of information storage layers store information about the number of information storage layers in each information storage layer. Accordingly, information about the number of information storage layers can be detected from any information storage layer.
  • information about information storage layers which is necessary upon data recording, must be recorded in a user data area because data recording or reproduction may randomly occur regardless of the sequence of physical addresses of basic recording units.
  • the information about the information storage layers can also be recorded as a groove wobble. In this case, upon data recording or reproduction, the information about the information storage layers can be reproduced using a push-pull channel signal.

  • an information storage medium in an information storage medium according to the present invention and a method of recording and/or reproducing data thereon, even where a user data area has no groove wobbles, data can be effectively recorded and/or reproduced using the methods described above, so as to provide information about the user data area, for example, information about whether the information storage medium includes a single layer or a plurality of layers, or information about information storage layers.
  • the present methods are effectively applied to reproduction-only information storage media having no groove wobbles, enabling reliable data reproduction.
  • information about a user data area can be recorded on recordable information storage media using the present methods in addition to a method of recording data on a groove wobble.

Abstract

Dans un support de stockage d'informations, des informations relatives à une zone de données utilisateur dans laquelle des données utilisateur sont enregistrées, sont enregistrées dans au moins une zone juste avant et dans une zone juste après une unité d'enregistrement de la zone de données utilisateur. Selon un procédé d'enregistrement et/ou reproduction de données par un support de stockage d'informations, des informations relatives à une zone de données utilisateur dans laquelle les données utilisateur sont enregistrées, sont lues depuis au moins une des deux zones juste avant et après la zone de données utilisateur, et la zone de données utilisateur est reconnue au moyen des informations lues.
