PURPOSE: A disk for writing basic development information and a regeneration method using the information are provided to avoid logical regeneration impossibility and to realize simple regeneration by using basic development information even if development by navigation fails. CONSTITUTION: A regeneration method of a disk comprises the steps of setting up a regeneration mode(S1), deciding the occurrence of an error while A/V(Audio and Video) data written on a disk are regenerated(S2), temporarily storing error position information in such a memory as an internal RAM(Random Access Memory) in a DVD(Digital Versatile Disk) player after retrying regeneration for several times(S3), deciding if regeneration in the basic development order by basic development information is needed(S4), reading out the basic development information from the disk if regeneration in the basic development order is selected(S5), regenerating the disk in the basic development order(S6), moving to a former navigation position if regeneration in the basic development order is not selected(S7), inputting a power off key or an ejection key(S8), and writing the error position information on the disk(S9).
