摘要： A double-sided optical disc, such as a DVD-18 disc, is formed with data tracks on each layer. The tracks on one side are oriented along one spiral while the tracks on the other side are oriented along a different spiral, the two spirals being oriented in opposite directions as viewed normally from the respective sides. This allows data to be read by a player seamlessly from either side of the disc without changing the direction of rotation of the disc while the data is being read. The player determines whether a newly inserted disc is oriented properly and, if necessary, the direction of the disc rotation is reversed.

摘要： Double-sided optical discs, such as a DVD-18 disc, are mass produced with data tracks on each layer. The tracks on one side of the discs are oriented along one spiral while the tracks on the other side are oriented along a different spiral, the two spirals being oriented in opposite directions as viewed from the respective sides, so that they are mirror images of each other. This allows data to be read by a player seamlessly from either side of the disc without changing the direction of rotation of the disc while normal data reading is proceeding. The process for making the discs includes forming master discs corresponding to the data layers and using these master discs to produce molded optical discs.

摘要： Methods and apparatus for recording on DVD-like recording media in which audio content is stored in a high-capacity multi-channel (e.g., six-channel) format are provided. Various channels may use various resolutions. A two-channel audio output may be derived from the multi-channel audio data stream during playback. To facilitate an accurate derivation, the mixing coefficients to be used in generating the derivation can be supplied along with the six-channel audio data.

摘要： An optical disc used for storing content includes a theft control area selected to render the disc unreadable. The disc must be exposed to radiation of a specific wavelength before it can be read by a regular device. The theft control area may include an area that contains data that instructs the device not to read the disc. This area includes a coating that changes its optical characteristics when exposed to the radiation. The material could be radiochromic or thermochromic. Alternatively, the theft control area includes an RFID device that includes an element that is radiation sensitive. In this embodiment, when the disc is irradiated, the element changes its electrical characteristics.

摘要： A double-sided optical disc, such as a DVD-18 disc, is formed with data tracks on each layer. The tracks on one side are oriented along one spiral while the tracks on the other side are oriented along a second spiral, the two spirals being oriented in opposite directions as viewed from the respective sides. A player with two laser read heads is provided for reading the disc. Each laser read head is disposed adjacent to a respective disc side. The data is read from the two sides, either in sequence from one side and then the other, simultaneously, or in some alternating fashion.

摘要： An apparatus for processing data and content includes at least one drive and a player (that may be implemented by software). At least some of the content is protected using a content scrambling scheme such as audio or video watermarking. The drive and player cooperate to operate in a lockable mode wherein if protected content is provided to the drive, the drive and player are interlocked so that the content is presented by the player only in accordance with consistent with protection scheme being used, and cannot be presented by any other player. Moreover, in the locked mode, protected content may not be accepted from any other drive. The drive and player are switched to an unlockded mode by presenting to the drive unprotected content.
