    Philips, Control Data to market half-height CDROM drive

     The folks at Laser Magnetic Storage International Co. (LMS), a
     new joint marketing venture between N.V. Philips and CDC, are
     bringing to market two half-height versions, both compatible
     with Philips' CM100 line.  The CM201 uses the same interface to
     connect to the PC bus. However, the new pared downed controller
     occupies a half slot.  OEM pricing for the CM201 production
     models will be about $320, says Robert Moes, LMS VP of CDROM
     marketing operations in NY.  The other LMS drive, the CM210,
     uses the SCSI, and will be priced at $440 in OEM quantities. A
     new CM153 half-card controller will cost about $70. 

    Both LMS drives have a formatted capacity of 600MB. By comparison, 
    most Japanese CDROM drives are 540MB. The average access time is
    500 msec. that's about where most CDROM drive manufacturers
    stand, give or take 100 msecs, industry observers note.  The 
    major difference between the two LMS drives is in data-transfer
    rates.  The SCSI version operates at 500KB/sec. the proprietary
    LMS interface controller card handles 176.4KB/sec.
