DVD-R/RAM combo drive
Panasonic presents a further break-through in the
DVD technology to the CeBIT with the new LF-D311: It is the first multi-function
drive, which controls both a describing and a reading of several times recordable
DVD RAMs and from uniquely recordable DVD R-S. The media created thereby fulfill
all request of the DVD forum and offer so the 100 percent compatibility not
only with DVD ROM drives, but also with DVD video Playern and - to recorders.
Thus the LF-D311 strikes a crucial bridge between the computer world and the
world of the entertainment electronics. Like that the drive for DVD and SINCE
IDIOMS is universally applicable: at home as high performance video recorders
and memories for the PC, in the office for economical storing and archiving
as well as in studios for professional developing and testing of master DVDs.
15 years experience with optical memory procedures
and 3 years with DVD RAM drives into the newest development of Panasonic flowed.
Switching between a laser with a wavelength of 650 nanometers (Nm) and one with
780 Nm guarantees highest possible compatibility with the LF-D311: The new DVD
RAM/R drive can read and describe both 4,7-Giga-Bytes(GB)-DVD-Rs and 4,7-GB-(9,4-GB-)DVD-RAMs.
Even the older 2,6-GB-(5,2-GB-)DVD-RAMs can be processed. The DVD technology
has crucial advantages opposite from CD: It offers a higher data security, the
capacity is zirka seven times more largely and the rate around a multiple more
highly. Only on a DVD a feature in perfect digital quality can be stored.
Additionally and does not only describe the LF-D311
reads DVD RAMs and DVD R-S, but is also read compatible to the formats DVD-ROM,
DVD video, DVD-R, audio CD, video CD, CD ROM and CD-R/RW. As CD-Drive it operates
at 24x rate.
With 4,7-GB-DVD-Rs the new DVD RAM/R drive achieves
a raterate rate of up to 11,08 megabits per second (Mbps). That corresponds
zirka the 9x rate from CD-ROMs (1 x). max. to 22.16 Mbps is it with 4,7-GB-DVD-RAMs,
with which they exceed the CD zirka around the 8x. The average access times
amount to 75 milliseconds (ms) for DVD RAMs and 65 milliseconds for DVD R-S,
DVD ROMs and CD.
The DVD-R technology is in the best way for it suitably, important
information permanently, surely, to store fast and space-saving for example
the data of banks, insurance, attorney offices, hospitals, offices and all dataintensive
companies. Nevertheless the information is easily accessible. Finally the most
DVD video Player and DVD ROM drives can DVD-Rs read and for the further handling
for example on computer fixed disks copy.
DVD RAMs can be again-described up to 100,000 times. They are
therefore particularly suitable data carriering for backup copies, to which
one would like to fall back regularly. Compared with tapes they offer the advantage
of the fast access. Owing to the various application type of the DVD RAM/R drive
also its target group is very far varied: Is useful for all private customers
and businessmen, who look an extensive and future-reliable DVD solution up both
for the video area and for professional storing and archiving of data.
The DVD RAM/R drive LF-D311 is available starting from September
2001 in the trade. Excluding OEM customers can the new DVD RAM drive over the
Panasonic Industrial Europe GmbH refer.
