Abstract:
A record carrier having first and second trick play signals, formed from first and second digital information signals, recorded at specific positions in slant tracks, the first digital information signal enabling replay in a reproduction apparatus at a trick play reproduction speed which equals n1 times the recording speed, and the second digital information signal enabling replay in said reproduction apparatus at a trick play reproduction speed which equals n2 times the recording speed, where n1 and n2 are integers unequal to each other and unequal to 0 and 1, characterized in that the first and second trick play signals comprise sync blocks of information of the first and second digital information signals, respectively, the sync blocks of the first trick play signal being written into first trick play segments, a first trick play segment comprising at least one sync block of the first trick play signal and at least one repetition of said at least one sync block, and the sync blocks of the second trick play signal being written into second trick play segments, enabling, during reproduction at said trick play speed n1 times the recording speed, reading of m1 sync blocks of the first trick play signal from first trick play segments during one revolution of a head drum of a reproduction apparatus, and enabling, during reproduction at said trick play speed n2 times the recording speed, reading of m1 sync blocks of the second trick play signal from second trick play segments during one revolution of the head drum, where m1 is an integer larger than 1, said first trick play segments being written in said tracks to enable a first read head of the reproduction apparatus to read at least one first trick play segment and a second read head of the reproduction apparatus to read at least one other first trick play segment during said one revolution of the head drum during reproduction at said trick play speed n1 times the recording speed.
