Analyses in Magnetic Recording of VHF Signals.

摘要

The technology of instrumentation recording is analyzed in respect to ultrawideband (vhf) recording requirements. Emphasis is given to problem areas that traditionally have prevented or retarded the advancements in ultrawideband tape recording. Concepts of vhf analog recording are discussed; problem areas are reviewed; and solutions are outlined. Extension of the upper frequency is realized by recording with higher tape velocities and at shorter wavelengths. Attention is therefore drawn to the driven-gap-spacer recording head, which is analyzed in relation to the recording of very short wavelengths.
