In connection with audio and video recording systems, the term long play usually stands for a longer playing time, mostly with a simultaneous reduction in the picture and / or sound quality. For magnetic tape-based systems such as B. video recorder or DAT audio recorder, this is done by reducing the tape speed , which inevitably leads to a deterioration in quality with analog recording. In digital systems, the data rate is usually reduced in long-play mode , which also degrades the quality.
One of the few exceptions is the long play mode of DV , in which the data rate and therefore the picture and sound quality is not reduced in long play mode. Instead, the data density is increased, which, however, leads to an increased susceptibility to errors and shortens the life of the tapes.
