1. Apparatus for recording data signals on a moving storage medium, comprising : - transducer means which scan the storage medium (11) and record data signals thereon along a recording track, - defect detection means which scan the storage medium before the transducer means, detect defect regions inhibiting the recording of data signals, and emit corresponding defect signals accordingly, also - control means which in dependence on the occurrence of defect signals interrupt the emission of data signals to the transducer means and bring about the recording of a special defect signal on the storage medium instead of the recording of data signals on the storage medium, characterised in that, - before the transducer means (17, 23, 25, 61, 89) the defect detection means (21, 48, 65) scan the storage medium (11) without modification of its storage properties, and - when a defect signal occurs the control means (39 to 63) emit a defect flag signal instead of the data signal to the transducer means (17, 23, 25, 61, 89) which accordingly record a defect flag signal along the recording track in accordance with the defect signal, and mark the respective defect regions in this way. |
