Video Disc Transducer System
An optical transducer system reproduces a videodisk record by rotating the disc at a low speed. A record guiding means is comprised of a ribbed gate region. The ribs engage the disc on opposite margins of the optical images ...
Video Disc Transducer System and Method
A video disc record having a spiral video record track which can provide reproduced video signals with a desired frame rate such as thirty frames per second while the disc record is rotated at a very low speed such as two ...
Record Medium Transducing Error Correction System and Method
In one exemplary embodiment errors due to tape flutter are overcome by recording along with the analog signal clock pulses having a rate sufficient for sampling of the highest frequency component of the analog signal. Then ...
Self-Correcting Record-Play System and Method
A 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 ...
Magnetic Recording System and Method
Magnetic recording circuitry supplies to the recording head in addition to the signal to be recorded a train of constant amplitude pulses of extremely short duration and of low duty cycle; for example, pedestal pulses of ...
