Abstract

A disk recording medium includes a lead-in area, a program area and a lead-out area. The program area includes: a first track on which a plurality of data signals each of which has a different index from the others is loaded; a second track on which a plurality of programs is loaded, whereby the plurality of programs consists of the sequential combination of the indices of at least one data signal among the plurality of data signals and each program has a different index from the others; a third track on which a data index table comprising the indices of the respective data signals and initial address information is loaded; and a fourth track on which a program index table comprising the indices of the respective programs and initial address information is loaded. The lead-in area is loaded with a table of contents comprising the initial address information and a plurality of pointers each of which is different from the others and designates the respective tracks of the program area and the initial position of the lead-out area. Thus, larger programs can be contained on a single disk and can be accessed without an operating program or an application program.
