ABSTRACT:
A magnetic storage indicator (40) is disclosed for use on a recording tape processing apparatus, such as a cassette winder (10). Magnetic storage indicator (40) comprises a recording head (50) and a downstream playback head (51). Signals received at the playback head (51) are transmitted to a pre-amplifier (60), an equalization circuit (70) and a record amplifier (80) and then back to the recording head (50) where the amplified signal is recorded onto the moving tape. If the oxide layer is on the side of the tape in contact with the record head (50) and the playback head (51) a feedback loop is completed, causing the circuit to oscillate. This condition is transmitted to a light emitting diode (48) indicating that the tape is properly wound.
