ABSTRACT:
A device to reproduce data stored on a recording medium 1 in sectors 14, each sector containing an address area 15 and a data area 16 being encoded in a different way. Address areas are decoded and checked by an address checking means 4 which stores data having an incorrect address into a first memory means 5 and data having a correct address into a second memory means 6. Data contained in the second memory means 6 is decoded by a data decoding means 7 in order to be reproduced. Data contained in the first memory means 5 is permitted to be reproduced in case that the number of successive sectors having incorrect address exceeds by one the difference between newly read correct address and the last correct address before the succession of incorrect addresses.
