ABSTRACT: Apparatus for recording information in a magnetic record carrier. When a record carrier (14) is inscribed for an nth time (n> 1), in which record carrier the information is recorded in first blocks (FB) in tracks (T1, T2, .,,) which adjoin each other and which are inclined relative to the longitudinal direction of the record carrier, each track containing at least one first block (FB1) of infor- mation and at least one second block (SB1) of tracking signals (f), only the first blocks of new information are written over the first blocks recorded previously in the tracks and the second blocks of tracking signals are not erased from the record carrier. These second blocks are employed for the purpose of tracking when the record carrier is inscribed for the nth time. In this way it is achieved that the new information is recorded exactly in the original tracks, so that perfect inserts can be made.
