    摘要: An optical disc includes tracking polarity information. The optical disc includes a clamping area, a lead-in area, a data area, and a burst cutting area (BCA). The BCA is present between the clamping area and the lead-in area and in which information regarding the optical disc is recorded, and the information is read before performing tracking in the data area. Accordingly, it is possible to obtain the tracking polarity information and/or reflectivity information without trial and error and directly record or reproduce user data in a data area of the optical disc.

    摘要: A method of recording data to an area including a defective ECC block of a DVD+RW, and an optical disk written in the recording method are provided. In the method, when data is recorded to an area including a defective ECC block, data recording ends at an ECC block right before the defective ECC block. Then, the data recording resumes from the last 8 channel bits of the ECC block immediately after the defective ECC block. Accordingly, recording/reproducing of data to/from an optical disk is consistently performed.

    摘要: An address information modulation method includes using a first characteristic of a first modulation method and a second characteristic of a second modulation method to modulate address information and/or additional information. Accordingly, a data amount of information, to access a disc, in a predetermined space of the disc is increased, and the modulated information is formed in a form of a wobble signal in a track. Here, the first characteristic of the first modulation method can be physical location information of an MSK-modulated signal, and the second characteristic of the second modulation method can be sign information of a second harmonic wave obtained by an HMW modulation, which synthesizes a cosine function of a basic frequency of a wobble signal with a sine function having a frequency that is a multiple of the basic frequency of the wobble signal. Therefore, where the address information is modulated, a plurality of information bits are loaded on a predetermined number of wobble or carrier signals to increase the amount of the information in the predetermined space, such that a physical length of the information needed in accessing the disc and reading the additional information thereof is shortened. Also, where a defect occurs, the resulting loss can be reduced such that addressing specifications for a small-sized high density disc can be satisfied.
