TOSHIBA XM-6401B/TXM6401F1 CD-ROM Drive 23
■Access Time •Average Random Access Time3:
80 msec typ. (40X mode)
•Average Random Seek Time4:
75 msec typ. (40X mode)
•Average Full Stroke Access Time5:
135 msec typ. (40X mode)
26-14X 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.
3Measured 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).
4Measured 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.
5Measured 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.
