Abstract: Administrating content of a digital video disc (DVD) having, on-disc, a database involves storing, externally to the DVD, information of the database. Based on the stored information, a check is made as to whether the DVD is operable to accommodate a proposed change to the content. The change on the DVD is made and the on-disc database is correspondingly updated, if the check determines that the DVD is so operable, e.g., if remaining resources of the DVD suffice to make the change. Preferably, the making of the change and the updating on-disc are interactively subject to the user's acceptance by means of a user interface.

Abstract: The more effective is the copy protection provided on a DVD, the greater is the likelihood that the copy protection will adversely interfere with legitimate uses of the disc. In a disc where the content is arranged in physical sectors, it is now proposed to provide subversive regions on the disc having a similar structure to genuine regions. A subversive region and a genuine region will each extend over one or more physical sectors. The subversive region will be provided with physical sector addresses which coincide with addresses of the genuine region. Navigational data will ensure that it is the genuine, rather than the subversive, region which will be accessed during normal play, but the subversive region will effectively hide the genuine region during copying.

Abstract: A technique for storing or backing up data to a removable media such as a CD or DVD with an enhanced probability that such data can be successfully read or recovered from such media subsequent to the writing/storing/backing-up of the data. This enhanced probability is achieved by storing the data to be copied to the media in multiple different physical locations of the media, such that a plurality of duplicate copies of the data exists on the media. Because there are multiple copies of the data stored on the media, the probability of being able to successfully read at least one good copy of the data is enhanced. For example, if one of the copies cannot be successfully read due to an unrecoverable error, another of the copies can be used to satisfy the read or restore operation. It is also possible to read all copies of the data in response to a read/restore operation, and any differences in the read data will indicate an error with at least one of the copies.

Abstract: A data recording apparatus recording data of a CD on an HDD in a manner such that the content of record in the CD is faithfully accounted for and shortening an operation time for a synchronized ripping operation. When the data recording apparatus reads, from the CD, track data managed by track, according to TOC, and records the track data onto the HDD, the data recording apparatus recognizes data unrecorded on the HDD, from among the track data recorded on the CD. This recognition process is automatically performed based on the TOC read from the CD, and album information replayed using the TOC and held by the HDD. The recording apparatus reproduces and outputs only the unrecorded data from the CD based on the recognition result concerning the unrecorded data. In this way, the data already recorded on the HDD is not transferred from the CD to the HDD. The operation time for the synchronized ripping operation is reduced accordingly.
