ABSTRACT:
A retroactive recording device, having a main recording medium, temporarily stores past information in a memory. In particular, an audio tape recorder includes a solid state retroactive memory which is operated continuously to temporarily store a past time interval of digital audio information. To begin retroactive recording, all or a portion of the past information stored in the retroactive memory is transferred to the recording medium. After transferring the desired past information, recording is continued in real time. In one embodiment, where the recording medium is a magnetic audio tape, temporarily stored past information is transferred to the audio tape by operating the audio tape transport mechanism at a higher than normal speed so as to catch up to present time. In another embodiment, where the recording medium is a non-volatile memory, temporarily stored past audio information is transferred to the non-volatile memory, and the present recording is continued in real time.
