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.

Abstract: A method of prerecording data for later playback upon demand, the data operatively associated with a data storage medium having a first play location and a last play location, the storage medium adapted for use with a player or transcriber such that the media has a predefined begin play point from which the data begins to be removed from the medium by the player wherein the begin play point can be located at any location on the media, the method comprising the steps of (a) on the media, locating the begin play point sufficiently remote from the first play location for accepting data therebetween, (b) impressing data on the media between the first play location and the begin play point, (c) impressing data on the media between the begin play point and the end play point, (d) further impressing data on the media between the first play location and the last play location, (e) engaging the player for locating the begin play point, (f) further engaging the player to locate the first play location, (g) initiating t
