(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)
