6-14X rotational speed is fixed for CD-audio (Red-Book) format. For the other formats, 17.3X
- 40X or 6X-14X mode is selected by command. The default value is 40X.
3
Measured by performing multiple accesses which refer to reads of data blocks over the whole
area of the media from 00:02:00 to 60:01:74 more than 3,000 times. Includes positioning, setting,
latency time, and ECC implementation time (if required).
4
Measured by performing multiple accesses which refer to seeks of data blocks over the whole
area of the media from 00:02:00 to 60:01:74 more than 3,000 times. Includes positioning
and setting time which has the same definition as HDD.
5
Measured by performing multiple maximum accesses which refer to reads of data blocks from
00:02:00 to 60:01:74 more than 100 times. Includes positioning, setting, latency time, and
ECC implementation time (if required). Typical value is for the average drive.
