PD dual phase (Phasewriter) technology had a brief surge of popularity in 1995 to 1996. PD was promulgated primarily by 'Toray and Panasonic. DVD-RAM is a much superior and advanced form I am especially interested in the Panasonic DVD-RAM system because it can read all my old PD disks (I have scores of PD disks because I was Visiting Professor for digital imaging in Japan in 1995-1996).

A DVD-RAM writer/player looks just like any CD-R unit.

We prefer the Panasonic because Panasonic was part of the PD Dual Phase technology, so has a head start into DVD-RAM technology.

A DVD-RAM disk is inside a protective shell. The assemblage is virtually identical to the PD disks on which DVD-RAM technology is based.

I am leery of many mail order places. How long have they been in business? I prefer to stay with a company that I have been buying from already for years. I trust the better companies will still be in business if I need to exchange anything. For these reasons we recommend MegaHaus, e-mail rgroover@metahaus.com

After all, FLAAR is a nonprofit research institute. It is rather rough on our budget if we have to pay high prices when the identical object is available from another place with guarantee, warranty, friendly service, and a company of ethical people.
