Disk recording medium and reproduction method and apparatus thereof

Abstract

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