Abstract

The initial aim of videodisc development was to produce a system that records audio/video information on a disc, replicates this disc accurately and inexpensively on plastic and finally, plays the replicas on home television screens by means of a disc player attachment. What made the videodisc so interesting is the potential combination of three properties: very low cost in high-volume duplication, very high information density, rapid acces to any portion of a long recording. Presently, two major disc categories are wel1 established: mass replica and write-one discs. Single headed players are almost exclusively used today. But, in some applications, where mainly access and interactivity are very important, two headed players are either used or presently being considered. Some new problems are surfacing, which are not of that much concern for the single-headed players. One of new problems is a time-based error (TBE) caused by recorded asymmetry, which will by discussed in this paper. Al so, the influence of this phenomenon on the medical images stored on the videodisc will be examined.
