This article was the first serious public look at the technical aspects of and market potential for CD-ReWritable (CD-RW). Known during its development as CD-Erasable (CD-E), CD-RW is an interesting chapter in the history of optical storage and, fanciful expectations of its promoters aside, continues to endure, long outliving most of its contemporaries.
Some suggest the conflict between Blu-ray Disc (BD) and HD DVD can be resolved by simply offering devices compatible with both formats. I’m not so sure. It’s easy to paint a rosy picture of peaceful coexistence, but compromise comes at a price. Pax Optical Hugh Bennett EMedialive, Apr 3, 2007 “I came not to bring …
The immediate question is, will Blu-ray Disc (BD) recorders, drives, and players read and write all types of CDs and DVDs? Will they clear the fog of application formats and content-protection measures? In last month’s column, I chastised BD device manufacturers for ducking clear answers to these questions. And surveying the broader situation, we see …
Change is unsettling. But, like it or not, change is once again upon us—this time with the arrival of next generation Blu-ray Disc (BD). Naturally, consumers and even professionals are apprehensive about this new format but, even so, BD’s promoters are doing an embarrassingly poor job of understanding and answering concerns.

Good grief. Just when recordable DVD hits the accepted speed limit we find a couple of joyriders stepping on the gas.

Socrates tells us that the unexamined life isn’t worth living. The same can be said for business. With scores of product launches and decades of market experience behind it, the optical storage industry has had ample opportunity for introspection. But, sadly, I see little evidence that past experience has entered the minds of manufacturers who, …

As Blu-ray Disc’s (BD) entrance draws near, I’m increasingly asked about its writable formats. How long will it take to record a BD disc? How much will its writing speeds increase in the future? How quickly will it get there? And, frankly, is there a way for the industry to avoid past problems and intelligently …

Let’s face it — writable CDs and DVDs are tough but they can be damaged. Scratches, scrapes, fingerprints, dust, and just plain crud can play havoc with reading and, especially, with writing. Dealing with these everyday realities in ways that keep discs realistically priced and marketable remains a challenge for product designers. Just Scratching the …

Here we go again. Despite the buying public’s four-year indifference to CD-ReWritable (CD-RW) technology, those involved in its creation just can’t take the hint. The latest attempt to increase the popularity of CD-RW involves extending its performance to 10X Constant Angular Velocity (CAV) and Constant Linear Velocity (CLV) writing speeds. Manufacturers must by now realize …
