摘要:
Provided is an information recording medium including a plurality of recording layers. Each recording layer may comprise at least one optical power control (OPC) area, and each OPC area is allocated so as not to overlap an adjacent layer in a given radius.
摘要:
A super-resolution information recording medium, a recording/reproducing apparatus, and a recording/reproducing method uses an information recording medium provides a super-resolution effect by fluid bubbles. The fluid bubbles are formed in at least a portion of the medium by a light beam radiated to reproduce a signal from the information recording medium. Accordingly, the super-resolution information recording medium has improved optical characteristics, so that better recording/reproduction is possible.
摘要:
A method of encoding information and a method of decoding information, and an apparatus to perform one or both methods, and an information storage medium on which to store the information, the method of encoding the information including encrypting data between two ECC-encoding operations, and the method of decoding the information including decrypting data between two ECC-decoding operations.
摘要:
Provided is an information storage medium that has a plurality of recording layers, a recording/reproducing method, and a recording/reproducing apparatus. In the information storage medium, each of the plurality of recording layers includes an inner circumference zone and a data zone, and at least one of the recording layers includes, in the inner circumference zone, a temporary disc management area (TDMA) for recording information about a defect detected in the data zone, wherein a size of the temporary disc management area allocated on an upper layer is greater than the size of the temporary disc management area allocated on a lower layer.
摘要:
A method of determining an optimum reproduction condition of marks recorded on an optical recording medium that in which the length of at least one of the marks is smaller than a resolution of a pickup. The method includes obtaining an optimum reproduction condition of a mark having a length which closely approximates the resolution of the pickup, and determining the optimum reproduction condition of the marks using the obtained optimum reproduction condition.
摘要:
An information storage medium is provided. The information storage medium includes a user data area on which user data is recorded, and a temporary disc management area on which a space bitmap representing a recording status of at least one recording/reproducing unit block of the user data area is recorded. The space bitmap including information about an additional space bitmap which is assigned in response to a space of the space bitmap being insufficient to represent the recording status of the at least one recording/reproducing unit block of the user data area.
