Criticism
UMDs offer large capacity and the capability to store quality audio/video content; however, the format's proprietary nature and the lack of writers and blank media has made adoption difficult. In comparison to Sony's MiniDisc format, there are a number of features lacking; the sliding shield which prevents direct disc contact on MiniDiscs is absent from all UMDs released, though it is an option according to the ECMA specification. PSPs were also not made compatible with MiniDiscs.
