A credit card size record/playback apparatus (figure 1) which permits recording of audio information of at least two minutes in duration in a package configuration which is entirely self-contained is disclosed. In a preferred embodiment, the apparatus includes a suitable microphone (27) and speaker (25) for operation in record and playback modes, respectively. Liquid crystal displays for indicating time of day (24), date (32) and message count (36) and alarm or event plan capability may also be provided. Switches control the record (22) and playback (20) operations, as well as searching (46, 48, 50, 52) for and identifying different messages or message events contained in the recording. The invention may also be configured for operation in only playback mode, without recording over or erasing the recorded message, such as for use in conjunction with on-site marketing of products in retail stores (figures 12-13). A voice card version (figures 6-8) and a phone attached version (figures 10-11) are also disclosed. |
