A disk recording medium has a lead-in area, a program area and a lead-out area. The program area includes a first table area where a first index table consisting of a plurality of first indices and address data is recorded, a second table area where a second index table consisting of a plurality of second indices and address data is recorded, a first data area where a plurality of first programs consisting of first data are recorded according to an index of the plurality of first indices of the first index table, and a second data area where a plurality of second programs consisting of second data and an index table of the first programs related to the second data are recorded according to an index of the plurality of second indices of the second index table. The reproduction method reproduces the data of the program selected from a disk recording medium having the above record format, to thereby record thousands of programs onto a single disk, directly access a large amount of programs without an operating or application system, and enable high speed accessing.
