      Here is a lot of good info about DVD+RW.

      From what it says there, DVD+RW is both cheaper and more compatible than DVD-RW, for about the same capacity. DVD+RW uses a slightly different technique that reduces gaps between data to give compatibility with the "vast majority" of existing DVD players. It is also apparently more flexible in burning compatible discs, 7x faster to close the session, and allows erasing of individual sections, rather than just the whole disc.

      HP are shipping their first dvd100i DVD+RW drive this month for US$599. DVD+RW media will reportedly sell for about US$16 (compared to the US$24 I've seen for DVD-RW media). Philips have announced their standalone DVD+RW unit, and will ship the bare drive in October.

      Apparently, initial units will only support DVD+RW/DVD-ROM/CD-R/CD-RW/CD-ROM, but DVD+R (analogous to DVD-R, but apparently also cheaper/more compatible) is promised shortly via a firmware upgrade. DVD-R media support may also be available.

      FWIW, my own experiences with DVD-R are mixed; 2 of the 4 DVD players and DVD-ROM drives I've tried DVD-R discs with would not recognise the discs at all. I plan to get a dvd100i as soon as they're available :-)

  19. Writable DVD by JBob-S · · Score: 5, Informative

    Back when DVD-ROMs were first developed, pleas to include "linking areas," also called "run-in" on magnetic media, were ignored. This meant that there would be no space to write bits to allow the data clock to be recovered. This is not a problem with a continuously written disc, as the "earlier" data can be used.

    However, with most technologies, the start of writing can vary hundreds of bits from its nominal location. This means that if you write sector 1, and later write sector 2 on its tail, there is no way to align the data clock to the data in time to read the data of sector 2, since the first bits are used to recover the clock.

    DVD-RAM addressed this problem by introducing a new format. There are small embossed address headers to mark where each sector might be, and a small written run-in for each recorded sector. This media is highly susceptible to scratches, since the embossed headers are easily obscured by dust or a scratch. Also, having the embossed headers means that these discs are INCOMPATIBLE with DVD-ROM drives.

    DVD-RAM discs also use land/groove recording. This means changes to the servo mechanism just to follow the track. A DVD-ROM drive must add in special reader circuitry to handle the data coding, different block architecture (ROMs use blocks of 16 sectors), different servos for land/groove structure, etc. DVD-RAM is endorsed by the DVD Forum, so is the "official" format.

    DVD-RW is also endorsed by the DVD Forum, but for video use. Its intended application for reliable use is to not put data in the first block where you first start writing (it becomes your run-in). The "link point" where writing begins and ends occurs about 1.5 sectors into the 16 sector block. This means that the first 1.5 sectors, while readable, have unrelated data to what you just recorded! Also, some amount of the beginning of what you did write will be unreadable because the data clock needs to be recovered, and the words synchronized to a sync mark. Realistically, the first two sectors will be trashed in any sector that contains a link point. These sectors are recoverable by ECC, but it severely reduces the amount of recovery that can be done on your real data!

    DVD-RW uses a shallow, low frequency, wobbled groove with some high frequency "ticks" (occurring at a low frequency) to gain some positional accuracy. These ticks are extremely susceptible to dirt, etc.

    Overall, DVD-RW is best used as a re-usable DVD-R.

    DVD+RW uses a shallow wobbled groove. However, this wobble is a continuous high frequency, and uses phase modulation to contain address information. The link point is a few bytes from the end of the sector, meaning that only a few bytes are sacrificed to the ECC gods (instead of 4K in the case of DVD-RW), and sufficient data exists to act as the run-in for the newly written sector.

    The logical layout of DVD+RW is identical to the logical layout of DVD-ROMs. Any drive that conforms to the DVD-ROM standards will read a DVD+RW disc. Unfortunately, some manufacturers took shortcuts (like assuming a low reflectivity disc is a dual layer disc, rather than reading the proper parameter from the media).

    The design characteristics of DVD+RW are such that it works well for randomly written data, and is compatible with DVD-ROM drives.

    In short, DVD-RAM only works if the reader was deliberately designed to read it. DVD-RW is readable by properly designed ROM readers, but is a very fragile format. Finally, DVD+RW is readable in properly designed ROM readers, and has the most robust inherent design.

    Standards that describe these DVD formats are available from ECMA.

    Both drives are quiet, and are multi-read compliant (exception: The Pioneer does NOT read DVD-RAM)
    DAE is surperb for either drive.
    I'm using both of them and can't find any bad habits about either. If the Panasonic did CDR it would be perfect (have to wait 'till January, I guess).
    I've tried the resulting DVDs made from both the Pioneer and Panasonic machines on Sony (including PS2), Panasonic, Pioneer, and Toshiba DVD home players and all work great with the exception of DVD-RW media, not all players will recognize DVD-RW.

    The DVD+RW from HP and Sony probably won't be available on the market for another 2-4 months.
    Panasonic will be releasing a "Super Drive" in January that does DVD-R, DVD-RAM and CDR(W).
    Pioneer is releasing a table top model in the Fall, the PRV-9000.

    It should be noted, if you have a Mac, your only real choice is the Pioneer DVR-A03 with Roxio's Toast Titanium. At this time, only the DVD-RAM side is supported by the MAC (Software Architech SAI DVD-TUNEup has unreleased beta drivers for the DVD-R side).
