The pits are produced by a laser or by a stamping machine and are read by a low-power laser and a photocell that generates an electrical signal from the varying light reflected from the pattern of pits.
In optical recording systems, sound waves modulate a beam of light; the sound track, which may be of variable density or of variable width, is a photographic record of the varying light.
** The suddenly personal image is surreal, as is the premise, two poems later ("If, My Darling"), that his darling has leaped into his head, to "find herself looped with the creep of varying light, / Monkey-brown, fish-grey, a string of infected circles / Loitering like bullies, about to coagulate".
