ABSTRACT:
A recording arrangement for recording trick mode information in portions of tracks includes at least two recording heads (A, B). Trick mode information recorded in the portions in the tracks enable a trick mode during reproduction in a reproducing arrangement having reading heads (50) for reading the trick mode information from the tracks, the reading heads including at least a first and a second reading head (A,B) located at the circumference of a head drum, and where the transport speed of the record carrier (40) in the said trick mode being n times the nominal transport velocity during normal play reproduction where n is an integer and comprises a divisor number p larger than 1. The trick mode information is recorded in such a way that in a group of 2p tracks (T.sub.2 to T.sub.7) the trick mode information is recorded in a portion of a first (T.sub.2), second (T.sub.3) and a third track (T.sub.5) in said group of 2p tracks, the first and second tracks (T.sub.2,T.sub.3) being neighboring tracks, the trick mode information stored in the portion (P.sub.1) of the first track (T.sub.2) being different from the trick mode information stored in the portion (P.sub.2) of the second track (T.sub.3), the trick mode information stored in the portion (P.sub.3) of the third track (T.sub.5) being equal to at least part of the trick mode information which is stored in the portion (P.sub.2) of one of the first and second tracks (T.sub.3).
