CD Burners with Built in Compression 248
EconolineCrush writes "Bored of new CD-R/RW drives that only seem to decrease burn times by a few seconds over their predecessors? Check out this review of Plextor's PlexWriter Premium over at The Tech Report. With an advertised CD-R burn speed of 52X, the PlexWriter is certainly fast, but its ability to encrypt the contents of burned data CDs and squeeze nearly a Gigabyte of data onto a 700MB disc is what sets it apart from other high-speed burners."

It supports all other formats as well, is faster than many other CD writers and can also read copy protected music CDs. Plextor is back to its old heights in providing a quality product and moves all OEM stuff back into in the shadow.
They were the first who recognized that a black interior decreases the bit error rate. They also provide good support. They once sent me a new ROM for no price.
They also have DVD writers and the only reason why they do not support this variable pit length feature there is probably because they haven't ordered bigger flash ROMs yet.
Yes, the pit length can be set in such a way that 1.2 GB fits on a CD-R or you can change it to 900 MB and get a good chance that it can still be read by others CDROM drives.
They also sell the CD writer with analyses software, so you can check the quality of your burnings.

Using this overburned discs... (Score:3, Informative)
To test compatibility, I burned four discs: Two data discs and two audio discs, with one of each at the 120% setting and one of each at the 140% setting. I then tried these discs in just about any player I could find. For data discs, that meant copying all the files off the disc onto the hard drive to make sure they could all be read. For audio discs, that meant making sure every track on the disc played properly.
The data discs were somewhat disappointing; out of seven optical drives tested, only two could successfully copy the files from the 120% disc, and none of the drives could copy from the 140% disc. Some drives couldn't even get a directory off the discs, while others failed part of the way through the file copy test. There was no rhyme or reason to the successes versus the failures, either; the two drives that "won" the test were a BTC 48X burner and a Hitachi DVD-ROM drive. The failures included a DVD/CD-RW combo drive, a Pioneer DVD-RW drive, a Sony DRU-500A DVD+/-RW recorder, and the LiteOn burner used in the benchmarks.
The audio discs were both more successful and more surprising. I tried these in three different computer drives, a bookshelf stereo system, a component DVD player, and two car stereos (one OEM Nissan, one my venerable Aiwa CDC-MP3). One of the computer drives recognized both discs, and did OK until near the end of them (failing to play the last two tracks on the 120% disc, and the last four tracks on the 140% disc). Another computer drive wouldn't play them at all, and a third played the entire 120% disc but couldn't play the 140% disc at all.
The bookshelf system and the component DVD player achieved identical results: Both played the 120% disc without any issues, but wouldn't even recognize the 140% disc. Perhaps the most surprising of all was the car CD players; both of them played every track on both discs. I was surprised enough that the wunderkind CDC-MP3 pulled this off, but an OEM Nissan player? Crazy.

It's encryption and compression... (Score:5, Informative)
GigaRec
The other special feature is GigaRec, which enables the PlexWriter to squeeze up to 40% more data than normal onto a piece of media. The process works by shortening the length of the pits being written to the disc; shorter pits means more pits fit on the disc, and more pits means more data. The problem, of course, is that because these pits are shorter than the standard for data or audio CDs, compatibility with other drives may be hit or miss. Plextor does guarantee that the PlexWriter Premium will read any GigaRec disc, but they make no guarantees about other drives.
So basically this will never catch on. The standard CD format is waaay to entrenched to be replaced. Other than for backup purposes, why would you want to burn a disc that's almost guaranteed not to work on another CD-ROM? The last thing need is another incompatible format of disc to worry about.. (DVD+RW, DVD-RW, DVD-RAM, etc)
SecuRec
Now that we've evaluated the drives' performance, let's take a look at a couple of the features that make the PlexWriter Premium so special. The first of these is SecuRec, which encrypts data before it is written onto the CD. You specify a password before beginning the write process, and once the CD is written, you need that password in order to view the recorded data. If the password is ever lost, so is the data.
There are a couple of limitations with the SecuRec feature. First, discs need to be recorded in DAO (disc-at-once) mode, so you can't burn multiple sessions of encrypted data, and as you might expect, only data CDs (not audio CDs) are supported. Second, in order to view the data, you need a copy of Plextor's SecuViewer software. This isn't that big a deal for Windows users, as the program is freely downloadable from the Plextor website. Linux and/or Mac users, however, are out of luck as far as I know, as SecuViewer isn't available for operating systems other than Windows. Just so there's no confusion, I'll point out that while you need a PlexWriter Premium drive to create a SecuRec disc, any CD-ROM drive can read one with the SecuViewer software and the proper password.
How this is better than a secure install program has got me... There's no real innovation here except that the encryption is moved to the CD Burning software. There are already quite a few tools to build installers that encrypt the installers and prompt for password to extract/install.

Suppose you're squeezing an extra 30% of data on the disc. I'd expect it's at least that much more likely that a scratch, excessive heat, time, or whatever would turn your backup into a coaster.
This is a bit different than the increase in HD platter density. With HDs, where the product includes both the rw mechanism and the media, the manufacturers had to implement stricter quality controls and test their media to tighter specs as they squeezed more data on the same amount of surface area. (And even still, reliability of IDE drives is poorer). In the case of these "compressed cds", the media is the same, and the manufacturers haven't tested its reliability when used with higher-density pits.
Maybe over time we'll see CD-R media that's been tested/certified for this standard (just like we now have media that's certified for various burn speeds). But until then I certainly wouldn't trust a compressed CD-R with any important data. (Or, I'd at least trust it far less than I do an uncompressed one)

We've dealt with backwards compatability issues before--remember when CD-RW came out? People will accept that, to read a 140% disk, they need a 140% or better reader, and life will go on. The problem is, if the specs are kept proprietary, I doubt any demand will be there for this technology.
