摘要

A recording apparatus for recording an information signal on one or more tracks on the recording medium 30 is disclosed. The information signal includes packets that occur irregularly as a function of time in the serial data stream of the information signal. The apparatus includes an input terminal 1 for receiving an information signal, a channel coding unit 6 for channel coding the information signal into a channel coded information signal, and a writing unit for writing the channel coded information signal to one or more tracks on the recording medium. It includes (8). The channel coded information signal includes an information frame. An information frame can be recorded in a group of n consecutive tracks Tr0 to Tr11 when the recording device is a spiral scanning type recording device and n is an integer greater than one. The apparatus further includes a time stamp (the time stamp generator unit (14,20,24) for generating a TS _i in relation to the moment generated the packets contained in the incoming signal information. In addition, composite packet (P _i ') There is a combining unit 4 which combines the packet and the corresponding time stamp to obtain, the time stamp generator unit comprising a counter 20 which generates a continuous cycle of successive count values, said cycle on said recording medium. Coincides in time with recording successive frames on one or more tracks, in response to detecting the occurrence of a packet in the information signal, a time stamp is generated for the packet, the time stamp being counted at the moment of occurrence of the packet. It has a predetermined relationship with the count value of the means.
