A method and a non-volatile memory apparatus for cloning prevention is provided. The non-volatile memory apparatus includes an Enhanced Media Identification (EMID) area, which is located in a specific area of the non-volatile memory, and stores an identification for identifying the non-volatile memory; and an EMID encoder for modifying the identification by a preset operation in conjunction with an arbitrary value, wherein the EMID area includes a first area in which reading by an external device is prevented, and a second area in which reading from the non-volatile memory by the external device is permitted in response to a read command.

Non-volatile memory for anti-cloning and authentication method for the same

A method and a non-volatile memory apparatus for cloning prevention is provided. The non-volatile memory apparatus includes an Enhanced Media Identification (EMID) area, which is located in a specific area of the non-volatile memory, and stores an EMID for identifying the non-volatile memory; and an EMID encoder for modifying the EMID by a preset operation in conjunction with an arbitrary value.

An information storage medium which stores data structures supporting multi-angles includes clip AV streams for respective angle data of multi-angle motion picture data. As additional information for each clip AV stream, clip information is recorded on a separate storage area from that of the clip AV streams. The clip information includes jumping-point information for jumping into another angle. Each of the clip AV streams may be recorded in a contiguous recording area, or divided into smaller interleaved units that are interleaved with units of the other clip AV streams.

Information storage medium having multi-angle data structure and apparatus therefor

An information storage medium on which multi-angle data is recorded includes at least two clips in each of which video object data for an angle of the multi-angle data is recorded. The at least two clips are recorded in contiguous areas of the information storage medium.

Information storage medium with structure for multi-angle data, and recording and reproducing apparatus therefor

A recording method for use by an apparatus and/or which is encoded on a computer readable medium includes selecting a defect management on mode or a defect management off mode that indicates whether defect management is to be performed or not while data is recorded in the recording medium, recording the data in the recording medium while defect management is performed on the recording medium, if the defect management on mode is selected, and recording the data in the recording medium without defect management, if the defect management off mode is selected.

Recording/reproducing method, recording/reproducing apparatus, optical recording medium, and computer readable recording medium having recorded thereon program for the recording/reproducing method

An information storage medium includes areas of disk-related information having disk-related information to record or reproduce data with respect to the information storage medium, wherein the disk-related information includes common disk-related information and changeable parameter information, and the areas of the disk-related information are arranged according to information about the changeable parameter information.

Information storage medium and method and apparatus for recording and/or reproducing pointing information

A disc having an updatable defect management area used by an apparatus for managing defects on the disc, the disc including a user data area which includes user data, a spare area that is a substitute area for a defect existing in the user data area, and an area in which are recorded an address of data that is last recorded in the user data area and an address of a replacement data recorded in the spare area. Accordingly, the disc defect management method and apparatus are applicable to a recordable disc such as a write-once disc while effectively using a defect management area of the disc.

Method of and apparatus for managing disc defects using temporary defect information (TDFL) and temporary defect management information (TDDS), and disc having the TDFL and TDDS

A write once disc includes a defect management area that is present in at least one of a lead-in area and a lead-out area; a temporary defect management area that is present in at least one of the lead-in area and the lead-out area; and a drive & disc information area that is present in at least one of the lead-in area and the lead-out area. Information regarding the locations of temporary defect information and temporary defect management information is recorded in the drive & disc information area, the temporary defect information and temporary defect management information, which includes drive & disc information, are recorded in the temporary defect management area, and temporary defect information and temporary defect management information, which are lastly recorded in the temporary defect management area, are recorded in the defect management area for disc finalization.

Method and apparatus for managing disc defect using temporary DFL and temporary DDS including drive and disc information, and disc with temporary DFL and temporary DDS

An optical disc includes a read-only area having a first wobble, which is a data wobble formed in the read-only area for only reading, a readable/writable area having a second wobble, which is different from the data wobble, and a connection area between the read-only area and the readable/writable area having a third wobble having the same frequency as one of the first and second wobbles.

Optical disc

A disc with a temporary defect management information area and a defect management area includes a defect management area that is present in at least one of a lead-in area, a lead-out area, and an outer area, a temporary defect information area which is formed in the data area and in which temporary defect information is recorded, and a temporary defect management information area which is present in at least one of the lead-in area, and the lead-out area. Accordingly, it is possible to record user data in a recordable disc, especially, a write-once disc, while performing defect management thereon, thereby enabling efficient use of a defect management area having a limited recording capacity.

Disc with temporary disc definition structure (TDDS) and temporary defect list (TDFL), and method of and apparatus for managing defect in the same

An apparatus for reproducing a recording medium having a recorded defect management area. The apparatus includes a pickup reading data from a recording medium and a controller controlling the pickup to read data on the recording medium and determining whether the recording medium contains predetermined data, recorded in response to a finalization command, to prevent recording with respect to the recording medium. The controller determines whether an area of a temporary defect management area not having defect management data includes the predetermined data by checking whether the temporary defect management data is filled with repetitions of a predetermined value.
