(5) Access Time (Typ.)
Average Random Access Time*3 95 ms (Max.24X)
110 ms (10X)
Average Random Seek Time*4 90 ms (Max.24X)
100 ms (10X)
Average Full Stroke Access Time*5 180 ms (Max.24X)
200 ms (10X)
*1: All CD formats, except CD Red book (audio), require additional application specific software
and/or hardware. The CD-ROM drive referenced 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.
*2: Max 10X rotational speed is fixed for CD-audio (Red-Book), CD-RW, VIDEO-CD format.
For the other Formats, it is Max.24X speed but 20X or 16X speed is selectable by command.
*3: Measured by performing multiple accesses which means reads of data blocks over whole
area of the media from 00 min. 02 sec. 00 block to 60 min. 01 sec. 74 block more than 3000
times. Includes positioning, setting, latency time and ECC implementation time (if required).
*4: Measured by performing multiple accesses which means seeks of data blocks over whole
area of the media from 00 min. 02 sec. 00 block to 60 min. 01 sec. 74 block more than 3000
times. Includes positioning, setting time which is same definition as HDD.
*5: Measured by performing multiple maximum accesses which means reads of data blocks from
00 min. 02 sec. 00 block to 60 min. 01 sec. 74 block more than 100 times.
Includes positioning, setting, latency time and ECC implementation time (if required). Typ.
value is for the average drive.
