Abstract

PURPOSE: To reduce the influences resulting from dusts of flaws by recording more than two tracks with recognizing portions which are indicative of the recording density or type of data.
CONSTITUTION: GCR burst 21 and ID burst 22 are recorded in 3014 Fci in a sixth track. Similarly to a PE system, the record starting position and length are standardized so that they can be easily recognized when read. ARA burst 24 and ARAID burst 25 are intrinsic to a GR system so that they are used in determining the apmlification gain when read. A data portion 26 is recorded in the maximum recording density of 9042Fci
