Show moreA transducer head configuration is utilized which is operable by means of recording pulses of extremely short duration and of low duty cycle. Provision is made for reading the recorded magnetization between recording pulses and correcting same pulse prior to substantial movement of the record medium relative to the transducing gap.

Show moreAn offset carrier longitudinal scan recording and reproducing system for television signals wherein an amplitude modulated video signal is derived from a television receiver and converted to an offset carrier with a full upper sideband and an attenuated vestigial lower sideband. A direct or offset carrier audio signal may be recorded on the same channel with the offset carrier video signal. During monitoring and playback, the offset carrier is heterodyned to a television broadcast frequency or intermediate frequency and coupled into the television receiver. The same receiver may simultaneously supply video I.F. and audio F.M. signals for recording, and monitor offset carrier audio and video signals supplied to the recording head to facilitate recording adjustments.
