ABSTRACT:
An apparatus for recording information signals in a track (T.sub.i) on a record carrier (2) is disclosed, comprising an input terminal (30) for receiving an information signal, a signal processing unit (32) for processing the information signal so as to make the information signal suitable for recording in at least one track on said record carrier, and a writing unit (33) for writing, after processing, the information signal in said at least one track on said record carrier, starting from a start position (s) viewed in the length direction of the record carrier and in a direction towards one of the end positions of the record carrier.
The portion of the record carrier (2) between said start position (s) and said one end position (L.sub.2) is fictitiously divided into a first sub portion lying (P.sub.1) adjacent the start position and a second sub portion (P.sub.2) lying adjacent the end position of the record carrier. When recording a first information signal, a first portion of a first information signal is recorded by intermittently recording blocks of information (B.sub.1,1, B.sub.1,2, B.sub.1,3, . . . ) in said track (T.sub.1) in said first subportion (P.sub.1) of the record carrier, starting from said start position (s). A second portion of the said first information signal is continuously recorded in said second subportion of the record carrier.
