Abstract: A high density disc having a data area which is set such that compatibility is secured in the same drive while maintaining a superior recording and/or reproducing feature. The high density disc has a center hole, a clamping area, a data area where user data is recorded, a lead-in area located at the inner side of the data area, and a lead-out area located at the outer side of the data area. In the high density disc in which the diameter of the center hole is 10 mm or more, the inner diameter of the clamping area is characteristically within a range of 20-26 mm. Also, the inner diameter of the data area is characteristically within a range of 35-40 mm. Therefore, while a conventional disc drive is still used, the size of the high density disc decreases and a recording capacity can be increased.

Abstract: A method of overwriting data in a linking loss area. The method includes the operations of (a) determining whether or not the first sector of a block in which it is desired for data to be recorded is a linking loss area, and if it is determined that the first sector is a linking loss area, reading the previous block; (b) modifying data type identification information of the last sector of the previous block after completing reading the previous block; and (c) recording data in blocks starting from the previous block. According to this method, based on determination of whether or not the first sector of the block in which it is desirable to record data is a linking loss area, data is recorded in the blocks starting from the current block or from the previous block so as to prevent errors in reproducing. By doing so, the method improves error correction effects.
