*1: All disc written in CD or DVD 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.

*2: Measured by performing multiple accesses which means reads of data blocks over whole area of the media from 0 (h) Frame to 1E7725(h) (4.089 Billion Byte:87 % of total area) Frame more than 3000 times. Includes positioning, setting, latency time and ECC implementation time (if required).

*3: 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).

*4: Measured by perfoming multiple accesses which means reads of data blocks over whole area of the media from 0 (h) Frame to 1E7725(h) (DVD-RAM Ver.2.1 Disc) Frame 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 0(h) Frame to 1E7725(h) Frame more than 3000 times.

Includes positioning, setting time which is same definition as HDD.

*6: 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.

*7: Measured by performing multiple seek which means seeks of data block over whole area of the media from 0(h) Frame to 1E7725(h) (DVD-RAM Ver2.1 Disc) block more than 3000 times. Includes positioning, setting time which is same definition as HDD.

*8: Measured by performing maximum accesses which means reads of each data block of 0 (h) Frame and 1E7725(h) Frame alternately more than 100 times.

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

*9: 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)

*10: Measured by performing maximum accesses which means reads of each data block of 0(h) block to 1E7725(h) (DVD-RAM Ver.2.1 Disc) block alternately more than 100 times. Includes positioning, setting, latency time and ECC implementation time (if required)
