Abstract

A laser beam recorder for analog data has been constructed having recording precision adequate for Fourier readout with 30 to 40 dB suppression of all spurious signal-like effects that could be caused from recording inaccuracies. It has been shown by Baker and Corcor-an (Ref. 1) that to attain such a high ratio of spurious effect suppression requires recording accuracies in terms of a small fraction of a recording spot dimension. Furthermore, the required spatial precision in line straightness, line parallelism, line spacing, vertical line alignment, scan velocity along lines, and other factors, must have an accuracy equivalent to 2 to 3 phase angle degrees of the highest recording frequency or 1 to 2 percent of a spot dimension. For the 6 micrometer spot employed, this spatial accuracy requirement amounts to 70 to 100 nanometers or 3 to 4 microinches.
