A Memorex DVD-R is a recordable disk that can be written once by a
computer or video recorder. Once a program or movie is recorded onto the
disk, it cannot be removed or altered in any way. Memorex is a widely
recognized brand name, producing audio and video tape, CDs and DVDs as
well as other recording materials. Recordable DVDs hold a lot of
information and often are used to back up important files on a computer.

Memorexs DVD-R come in a variety of colors. All are
recordable once by laser technology available in standard DVD burner
drives on computers that support DVD-R/RW blank media, in DVD RAM
recordable drives that only support write-once disks and in stand-alone
DVD recorders. The disks have a dye layer underneath a reflective
surface. The laser writing head on the DVD burner selectively darkens
areas on the dye layer to create the digital pattern that the reading
laser head scans.

Memorex DVD-Rs record audio files at 16x normal playing
speed and will record at slower speeds for video and HD video files that
may be more complex to record. Higher speed recording can be prone to
errors. Data files usually burn at higher speeds depending on the
quality of the DVD burner.
