(6) Transfer Rate

Sustained Block Transfer Rate

776-1,800 Block/s (10.3-24X CAV)

300-450 Block/s (4-6X PCAV)

Sustained Data Transfer Rate

Mode-1: 10.3X-24X CAV 1,552-3,600 KByte/s

4X-6X PCAV 600-900 KByte/s

Mode-2: 10.3X-24X CAV 1,769-4,104 KByte/s

( 1 KByte=210 Byte=1,024 Bytes, 1 MByte=220 Byte=1,048,576 Bytes)

(7)Access Time

Average Random Access Time*4	120 ms Typ (10.3-24X)
Average Random Seek Time*5	105 ms Typ (10.3-24X)
Average Full Stroke Access Time*6	170 ms Typ (10.3-24X)

(8)Spin up Time ( Focus Search Time and Disc Motor Start up Time )

2.0s Typ (10.3-24X)

(9) Data Buffer Capacity 2 MByte

*1: This drive write the data on the disc of CD-R, CD-RW format. However, in order to run applications that use these formats you must first have the required software and/or hardware.

*2: All disc written in CD formats, except CD-DA (audio), require additional specific

application software and/or hardware. This drive referred in the specification is capable of reading these data formats. However, in order to run applications that use these formats you must first have the required software and/or hardware.

*3: Data capacity when recording depends on the condition of the record and decreases from this occasionally.

*4: Measured by performing multiple accesses which means reads of data blocks over whole area of the media from 00 min 02 sec 00 Frame to 60 min 01 sec 74 Frame (552.96 Million Byte:87 %

of total area at linear velocity of 1.3 m/s) more than 3000 times. Includes positioning, setting, latency time and ECC implementation time (if required).

*5: Measured by performing multiple seek which means seeks of data block over whole area of the media from 00 min 02 sec 00 Frame to 60 min 01 sec 74 Frame more than 3000 times. Includes positioning, setting time which is same definition as HDD.

*6: Measured by performing maximum accesses which means reads of each data block of 00 min 02 sec 00 Frame and 60 min 01 sec 74 Frame alternately more than 100 times.

Includes positioning, setting, latency time and ECC implementation time (if required)
