Lateral Disk Recording for Immediate Playback with Extended Frequency and Volume Range

The equipment for lateral disk recording can be attached to a reproducing turntable and provides means for recording on lacquer-coated disks. The records can be played immediately using a new high-fidelity pickup. The recorder operates on a maximum power of approximately one watt. A sapphire stylus, normally supplied for instantaneous recording on lacquer, is used. When the recommended technique is followed, records can be made comparable in quality with commercially produced transcription records.
