ULTRA-WIDEBAND, LONGITUDINAL MAGNETIC-TAPE RECORDING

International Telemetering Conference Proceedings / October 10-12, 1972 / International Hotel, Los Angeles, CaliforniaSignal frequencies from 100 kHz to 30 MHz with bias frequencies of 120 MHz and higher have been recorded longitudinally on magnetic tape with a SNR better than 15 dB. The upper frequency of zero-bias-recorded signals was 36 MHz at a tape velocity of 2800 ips. The recordings were reproduced on a standard Mincom wideband recorder/reproducer at 60 and 120 ips. This laboratory recording system includes a Newell-type tape transport, which has been redesigned to comply with requirements of higher tape velocity and faster acceleration. At present, this transport accelerates tape at a rate of approximately 8000 in/sec^2 to a maximum speed of about 3000 ips. The magnetic recording heads developed for this system represent the state-of-the-art in head design., These are combination heads having a ferrite core with Alfesil pole tips and an insulated conductive gap spacer.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
