RECORDING APPARATUS AND METHOD FOR RECORDING INFORMATION ON A RECORD CARRIER IN THE FORM OF CONTIGUOUS PIT-MARKS

摘要

A recording apparatus for recording channel symbols of a channel data stream on a record carrier ( 50 ), said apparatus being adapted for recording said channel symbols as a channel band (cb) of at least two symbol rows (sr) one-dimensionally evolving along a first direction (t) and aligned with each other along a second direction (r), said two directions constituting a two-dimensional lattice of symbol cells (sc) each being associated with a symbol area (sa) of the record carrier ( 50 ). To reduce the occurrence of leading and trailing edges of pit-marks in the recorded channel band, and in order to be able to write a small radial extent in said second direction in view of limiting cross-write effects, it is proposed to record a channel symbols in the form of a mark area (rpm) having a longitudial shape of a length in said first direction ( 1 ) substantially equal to the length of a symbol area (sa) in said first direction (t) and of a width in said second direction (r) being smaller than the width of a symbol area (sa) in said second direction (sa).
