This is something of a myth. You see, Sony's mechanism uses only one read laser. The other two lasers are used for tracking. The logic is, if either of the two tracking lasers say that the read laser is not aligned correctly, the entire lens assembly should be realigned. The Philips mechanism uses one laser. The logic is, if the read laser is not aligned correctly, the lens assembly should be realigned. If any of the three lasers in the Sony mechanism become incorrectly focused, the whole thing fails. The Philips mechanism cannot not suffer from this type of failure. A bonus side effect, the Philips mechanism is more resistant to skipping than Sony's. And contrary to your belief, it is the cheapest CD players that have three lasers, because Sony licenses its mechanism for significantly less than Philips. [...] | Where was it overheating?

Re: MD: Iomega CD Drive
There probably isn't a drive made that someone hasn't had problems with. My experience with this drive and my two friends' experience with Phillips SCSI drives are good. In general, most drives work pretty well as long as the computer they are connected to is working properly. Most problems that I have helped people fix with CD recorders are actually problems with other software on the hosting computer.

Stainless Steel Rat [EMAIL PROTECTED] wrote: You had a faulty individual unit. Philips CD mechanisms are generally better than Sony's. They are mechanically simpler -- one laser instead of the three in Sony mechanisms -- which makes them as a whole that much more reliable. I am guessing that your "bad experience" is with a particular model of HP CD writer. The problems there were not the CD mechanisms, which happened to be Philips mechanisms. HP underdesigned the cabinetry, which allowed the CD mechanism to overheat. When that happens the mechanism destroy itself. The fault was HP's, not Philips's. The problem is that my burner (HP7200i) will work OK (well, most of the times) if I use CD-RW media, but will *regularly* freeze while burning CDR's... The red light turns off, while the green one keeps flashing, the burning software freezes, and so does the computer itself. Do you know if these are the symptoms of what you say is the HP-related problem? I ask because I still have not found anyone who could help me, so sorry if this is off topic, but any help would be appreciated.

Re: MD: Iomega CD Drive 80 min?
I just stopped by Best Buy and picked up a ZipCd. They also had some blank CD-R that 80 minute, 700 mb. I hope this unit will work with those babies. I guess they are comming out with the 80 minute MDs so we can record the 80 minute CDs.

I don't think it's a rebranded drive, but it's supported in the latest Nero (www.ahead.de), and Adaptec's Easy CD Creator (you get a copy of 3.5 Standard with the drive) - other burning programs will probably follow suit very soon.
