PHQ 88.002 06.09.1988 ABSTRACT: Method of and apparatus for successively recording EFM-modulated signals. A method of and apparatus for recording a first and a second EFM-modulated signal is described, which signals comprise EFM- subcode frames, the beginning of each EFM-subcode frame being marked by a subcode-synchronisation signal. In the track portion of a record carrier (1) intended for recording position-synchronisation signals are recorded by means of a track modulation which can be distinguished from the information pattern to be formed. During recording the subcode- synchronisation signals are maintained substantially in phase with the position-synchronisation signals (11), so that the track portions (14) in which the subcode-synchronisation signals are recorded substantially coincide with the track portions (140) in which the position- synchronisation signals are recorded. Recording of the first EFM- modulated signal (142) ends at a boundary position (144) which is situated at a predetermined position between the track portions (140) in which two successive position-synchronisation signals are recorded. Recording of the second EFM-modulated signal (143) begins substantially at the predetermined boundary position (144). (Figs. 1 + 11c).
