CLEANED, TESTED, WORKING PERFECT.
 
The FZ-506 is a double-sided, high-density, double-track type and its capacity is 1 .6M bytes, in unformat- ted mode. The read/write selection of the high density 1.6M bytes, 96 TPI and double density 1M bytes, 96 TPI disk can be carried out by changing either the motor speed (360 rpm/300 rpm) or transfer rate (500K BPS/300K BPS). In addition, as the data retrieval from 250K bytes. 48 TPI disk to 500K bytes, 96 ' TPI disk is possible, the former software packages can be read.
