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 the player to transcribe the data from the media between the first play location and the begin play point, and (h) allowing the player to transcribe past the begin play point for playing the data from the media between the first play location and the last play location.
