“…low densities. 9 One way to reduce these effects is to make use of the available very high linear densities to employ modulation techniques so that recording takes place in a restricted range of high densities. As an example, in an analogue system designed to operate between 50 c/s and 5 kc/s at a tape speed of 1 -25 inches per second, a tracking density of 30 per inch would be the maximum allowable in order to keep crosstalk at the low frequencies to an acceptably low level.…”

Reliable digital storage at linear densities as high as 20 000 bits per inch has resulted from an investigation establishing means of providing optimum recording and reproducing resolution. High linear densities make greater lateral densities practical by reducing interference between tracks. High lateral densities have been demonstrated: 1000 tracks per inch with special head structures, and 4000 tracks per inch with selective-erasure techniques. An area density as high as 32 million bits per square inch has been achieved.These developments remove some of the apparent limits of area density in magnetic recording, and place the emphasis on the necessity for improving reproducing techniques.
