Abstract

896,271. Magnetic recording methods. March 1, 1961 [March 10, 1960], No. 7426/61. Class 40 (2). A split-spectrum tape-recorder records the LF component directly, with heavy bias at the head 2, the H.F. component being heavily attenuated thereby, and the H.F. component, taken from a high-pass filter, HP1, on to a delay tape 9, which may take the form of a loop of tape on the flywheel which is connected to the main tape-drive capstan. The high frequencies, played back at 6 are recorded with light bias on top of the low frequencies at 3. In another embodiment (not illustrated), the main tape 1 is first fed past the delay heads 5, 6 and then, after erasing, over the heads 2, 3. A single head 8 is used for playback.
