DVD, DVD+R, DVD+RW?
What is a DVD?
DVD (Digital Versatile Disc) is a new storage medium that combines the convenience of the compact disc with
the latest digital video technology. DVD video uses modern MPEG2 data compression technology that enables
an entire feature film to be stored on a single five inch disc.
How good is the resolution of DVD compared with VHS?
The razor-sharp digital images have a resolution of more than 500 lines of 720 pixels per line. This is more than
twice as high as VHS and is even better than the laser disc. Its picture quality is easily comparable to the digital
masters produced in recording studios.
What can DVD+RW do?
DVD+ReWritable uses phase change media, the same technology on which rewritable CDs are based. A high-
performance laser is used to change the reflective properties of the recording layer; this process can be
repeated more than a thousand times.
What can the DVD+R do?
DVD+R (write-once DVD). Unlike a DVD+RW disc, this disc can only be written to once. If it is not finalized after
a recording, further recordings can be added to it. Old recordings can be later deleted but they can no longer be
overwritten. The deleted recordings (titles) are marked 'deleted title'.
Before this disc can be played in a DVD player, it must be finalized in the DVD Recorder+VCR. Once this process
is complete, no further recordings can be added.
What can my DVD recorder do?
Your DVD Recorder+VCR is a machine for recording and playing back digital video discs with 'two-way'
compatibility with the universal DVD video standard. This means:
• existing DVD video discs can be played on the recorder.
• recordings made on your DVD Recorder+VCR can be played on other DVD video players and DVD ROM
drives.
