Abstract:
A method for simultaneously receiving and supplying real time information signals while recording and reproducing the information signals on/from a disc like record carrier, comprising:receiving a first information signal for recording; processing the first information signal into a first channel signal for recording on the disc like record carrier the first information signal being converted into blocks of information of the channel signal, SFA/2&lE;size of a block of the channel signal&lE;SFA, where SFA equals the fixed size of a block of a fragment area; writing the first channel signal on the disc like record carrier wherein the writing includes writing a block of information of the first channel signal in the fragment area in a data recording portion on the record carrier the data recording portion being divided into fixed size fragment areas; reading blocks of information of second channel signal from fragment areas of the record carrier; processing the blocks of information of the second channel signal for obtaining a second information signal; supplying the second information signal while simultaneously receiving the first information signal, and recording and reproducing the channel signals in subsequent cycles, a cycle including: no more than one write action for contiguously writing a block of information of the first channel signal into a fragment area on the record carrier and one or more read actions for contiguously reading each action at least a portion of the block of information of the second channel signal from the record carrier.
