Abstract
A display apparatus is provided whereby a constant intensity of record is obtained notwithstanding substantial changes in the linear speed of the record member. The cathode ray sweep frequency is maintained at a constant rate commensurate with the highest speed of the record member. As the speed of the record member is reduced by a given factor, the number of scans of the cathode ray beam which are unblanked are reduced by the same factor.
