High-data-rate, spacecraft tape recorders.

Description of magnetic head designs, tape transport features, encoding techniques, bit error rates, and data rate capabilities of tape recorders used on board satellites for temporary storage of sensor data. Helical- and transverse-scan rotary head mechanisms used for wideband video signals from imaging systems are explained along with associated electronic circuitry. Decoding and decision procedures employed in multiple-track recorders are outlined, and deskewing electronics are discussed.
