Note :

1)Average random access time is the typcal value of more than 50 times including latency and error correction time. Test Disc : DVD : ALMEDIO TDV-520 / TDR-820

CD : ALMEDIO TCDR-701 / HITACHI HCD-1

*) Typical value defines a measured value in normal temperature (20 deg.C.) and horizontal position.
