Spirally wound video recorder recording carrier - has recording and playback element for several tracks, and head locates between tracks

摘要

A spirally wound recording carrier for storage of electrical oscillations and suitable for a video recorder has recording and playback element for several tracks. The recording carrier is wound so that it maintains an interval (a) allowing the recording or playback element to dip into a defined depth in this interval. The recording or scanning of the electrical oscillations takes place laterally on the element. Several tracks can be recorded on or played back from the carrier by displacement of the dipping depth. The interval of the recording carrier is determined by the intermediate layer of a narrower sheet. Its thickness corresponds to the interval required.
