A description is given of a process for determining defects on magnetic tapes, in which there is installed in a head drum, known from the prior art, an optical arrangement with the aid of which laser light illuminates the magnetic tape, and the evaluated signal is fed to an electronic counting arrangement. In this way, contactless dropout measurement is possible (Figure 2). <IMAGE>
