Design and specifications are subject to change without notice.
* Note 1 : It is recommended to write and
read the DVD-R, DVD-RAM, CD-R
and CD-RW discs using the drives
of the same model. If drives of dif-
ferent models are used in write
and read, discs of certain manu-
facturers or production lots may
not manifest the full performance.
* Note 2 : Only discs with a diameter of 120
mm are applicable.
* Note 3 : Use DVD-R, CD-R and CD-RW
discs that match the optimal writ-
ing speed. However, even if the
appropriate discs are used, an ad-
equate performance may not be
achieved depending on the disc
manufacturer or production lot
compatibility.
