Abstract

Provided are an apparatus and a method for recording on a recording medium images from a fiber-optic CRT. The apparatus includes a recording medium transport system, control electronics and a first-in, first-out memory. The use of the first-in, first-out memory permits incremental recording which is not limited by relatively long mechanical transport settling times. In operation, N lines of data are input to the memory, line-by-line, as the transport system increments the position of the recording medium and during settling time. When the recording medium has come to rest, these N lines of data are output sequentially from the memory in a first-in, first-out basis, with the CRT incrementing each line vertically on the recording medium for the total of N lines for each increment of the recording medium by the transport system.
