摘要：A format for the recording of trick play signals is proposed in which trick play segments comprising sync blocks of information of a trick play signal are recorded in groups of p successive tracks. At least first and second trick play signals are recorded on the record carrier. The first trick play signal is meant for reproduction in a reproduction apparatus at a reproduction speed n1 times the recording speed with which the trick play signal are recorded on the record carrier. The second trick play signal is meant for reproduction in the said reproduction apparatus at a reproduction speed n2 times the recording speed. Both trick play signals are recorded such that upon reproduction at said speed n1 times the recording speed m1 sync blocks of information of the first trick play signal and m1 sync blocks of the second trick play signal are read from the record carrier during one revolution of the head drum in the reproduction apparatus.
