MultiRead: Look for It.....................................................onlineinc.com Being able to identify easily the capabilities of a DVD-ROM drive at point of purchase can be difficult. Most consumers are not accustomed to scrutinizing detailed specification sheets and sales staff are not always well-informed. Something as specific as checking for CD-R compatibility can easily get lost in the shuffle. One way to provide a clear definition to the public of a drive's capabilities is by having consumers look for an identifying logo or term on the box or in advertising that captures complex concepts. "MultiRead" is such a helpful term. Created by the Optical Storage Technology Association (OSTA), a prominent manufacturers' and industry group that promotes the use of writable optical technology, MultiRead is a drive specification defining the logical and physical requirements of a drive that can read CD-ROM, CD-DA, CD-R, and CD-RW discs. Any DVD-ROM drive bearing the MultiRead logo or displaying the name MultiRead provides assurance that the unit reads CD-R discs. ------------------------------------------------------------------------ The OSTA CD-R/DVD-ROM Compatibility Study Since 1995, the CD Writable Physical Compatibility subcommittee of OSTA has undertaken a program of compatibility testing for CD recorders, media, and readers. The current effort by the group is a CD-R/DVD-ROM compatibility study designed to help manufacturers assess the ability of their DVD-ROM drives to read CD-R discs. Fourteen hardware companies are participating in the study, including Acer Peripherals, Hitachi, JVC, LG Electronics, Matsushita Kotobuki, Mitsubishi Electric, NEC Home Electronics, Philips, Pioneer, Samsung, Sanyo, Sony, and TEAC. The framework for the tests involves having DVD-ROM drives read a representative sample of fully-written 74-minute CD-R discs taken from an earlier OSTA compatibility study, as well as one pressed CD-ROM containing the same data set. Both the CD-R and CD-ROM media are played in the manufacturer's DVD-ROM drive to measure such parameters as average access time, average transfer rate, and read time, in addition to optional data verification and average error rates. The first round of testing is scheduled for completion in February 1998, followed by a formal report. Preliminary results presented at the OSTA meeting in San Jose, California on October 21, 1997, indicated relative success. More than 70 percent of the CD-R discs displayed an average access time within 10 percent of that of the pressed disc. Additionally, more than 90 percent of the CD-R discs arrived at an average data transfer rate within 10 percent of that of the pressed disc. Since many of the products used at that time were still in development, the final results are expected to become significantly better as market-ready products are evaluated.
