Abstract

The recording apparatus has a drive unit which reduces the scanning of the picture to a speed suitable for signal recording on a normal magnetic tape running at a normal speed and a rotating magnetic drum store records the signals from the tape a low speed, and delivers them at a high speed to the t.v. receiver. There is a slit diaphragm system with slits crossing each other at 90 deg. and moving at a relatively low speed which is used to scan the transparency. The slits may be included in endless moving bands mounted on systems of rollers.
