Summary:PURPOSE: A data recording medium, data recording apparatus and method, and data reproducing apparatus and method are effective when they are applied to a case where different kinds of time information or addresses exist mixedly. CONSTITUTION: An absolute time area is extended by means of a comparatively unimportant area such as a zero data area and/or a relative time area included in a Q channel contained in a subcode of a CD recording format. Concretely an absolute time is expressed by performing the BCD expression of the digits of '100 minutes' by means of lower 4 bits included in an 8-bit zero data area(ZERO). Thus, the absolute times covering up to the largest 999 minutes 59 seconds 74 frame can be expressed. Meanwhile, the identification information showing an optical disk of large capacity and high density, for example, can be expressed by means of higher 4 bits included in the area(ZERO).
