ABSTRACT:
A method of masking data on a storage medium for selective playback upon demand or for transcription to another medium is provided. The method comprising the steps of (a) determining the position of the start location on the storage medium, (b) determining the position of the stop location on the storage medium, (c) positioning at least one data track on the storage medium between the start location and the stop location such that the data track has, adjacent thereto, enough space or time for accepting a concealed data track, and (d) impressing data on the storage medium for generating the concealed track having a hidden recording area such that the hidden recording area contains concealed data which can be accessed upon demand for transcription to another medium or for playback. The present invention can be adapted for use with different storage media such as, for example, a compact disk, a read-only memory compact disk, a mini-disk, a photo compact disk or the like. More particularly, the step of impressing data on the storage medium for generating the concealed track further comprises the step of generating the concealed track by identifying a position within the gap relative to either location or time for working with a player or transcriber and impressing the concealed track on the storage medium at the identified position.
