I always had problems with their blank VHS videocassettes back in the 80s and 90s, so I wasn't expecting much when I bought Sony's brand of blank DVD-Rs. To my surprise they turned out to be a very good brand, and I have bought several hundred over the last couple of years that I've owned a home DVD recorder.

I like the fact that Sony makes their discs available in speeds 1x thru 16x because I still have a Panasonic DVD recorder that won't accept anything higher than 4x speed. So Sony's come in real handy for this reason.

I definitely recommend this brand to anyone who's shopping around...

The larger storage capacity of a DVD-R compared to a CD-R is achieved through smaller pit size and smaller track pitch of the groove spiral which guides the laser beam. Consequently, more pits can be written on the same physical sized disc. In order to write smaller pits onto the recording dye layer a red laser beam with a wavelength of 650 nm (for general use recordable DVD, versus a wavelength of 780 nm for CD-R) is used in conjunction with a higher numerical aperture lens. Because of this shorter wavelength, DVD-R and DVD+R use different dyes from CD-R to properly absorb this wavelength.
