The emergence of the tape cartridge and cassette as entertainment media prompts comparisons with the disc record. Factors which control the disc noise during production have been measured and are discussed and the geometric level limitation of a disc, occurring in an equalized player, is described. Both the level capability and the background noise of cartridge and cassette tape are measured and discussed. The dynamic range curves of each medium are compared by referencing to the audible background noise and examining the level capability. At present the disc record has the greater dynamic range.
