128 Everything You Ever Wanted to Know About DVD<br />
Samsung and C-Cube made a technology demonstration (not a product<br />
announcement) in October 1999 of a DVD-RAM video recorder using the<br />
new DVD-VR format (see the preceding DVD-RW section for more about<br />
DVD-VR). Panasonic demonstrated a $3,000 DVD-RAM video recorder at<br />
CES in January 2000. It appeared in the U.S. in September for $4,000 (model<br />
DMR-E10). At the beginning of 2001, Hitachi and Panasonic released DVD<br />
camcorders that use small DVD-RAM discs. The instant access and on-thefly<br />
editing and deleting capabilities of the DVD camcorders are impressive.<br />
Panasonic’s 2nd-generation DVD-RAM video recorder appeared in October<br />
2001 for $1,500 and also wrote to DVD-R discs.<br />
The DVD-RAM 1.0 format is standardized in ECMA-272 and ECMA-273.<br />
How Do I Remove a DVD-RAM Type 2 Disc from the Cartridge?<br />
Type 2 DVD-RAM cartridges allow the disc to be removed so that it can be<br />
played in standard players or drives. (However, most players and drives still<br />
aren’t able to read the disc; see “Is It True There Are Compatibility Problems<br />
with Recordable DVD Formats?”)<br />
First break (yes, break) the locking pin by pushing on it with a pointed<br />
object such as a ballpoint pen. Remove the locking pin. Unlatch the cover by<br />
using a pointed object to press the indentation on the back left corner of the<br />
cartridge. Data is recorded on the unprinted side of the disc—do not touch<br />
it. When you put the bare disc back the cartridge, make sure the printed side<br />
of the shutter and the printed side of the disc face the same direction.<br />
Most DVD-RAM drives will not allow you to write to a bare disc. Some<br />
will not allow you to write to a cartridge if the disc has been removed.<br />
DVD�RW and DVD�R<br />
DVD�RW is an erasable format based on CD-RW technology. It became<br />
available in late 2001. DVD�RW is supported by Philips, Sony, Hewlett-<br />
Packard, Dell, Ricoh, Yamaha, and others. It is not supported by the DVD<br />
Forum (even though most of the DVD�RW companies are members), but<br />
the Forum has no power to set standards. DVD�RW drives read DVD-<br />
ROMs and CDs, and usually read DVD-Rs and DVD-RWs, but do not read<br />
or write DVD-RAM discs. DVD�RW drives also write CD-Rs and CD-RWs.<br />
DVD�RW discs, which hold 4.7 billion bytes per side, are readable in many<br />
existing DVD-Video players and DVD-ROM drives. (They run into the same<br />
reflectivity and disc format recognition problems as DVD-RW.)<br />
DVD�RW backers claimed in 1997 that the format would be used only<br />
for computer data, not home video, but this was apparently a smokescreen<br />
intended to placate the DVD Forum and competitors. The original 1.0 for-
