How OROM Works
OROM works on an entirely new and
patented approach to optical data
storage. Current optical data storage
devices like CD-ROM drives read data
one bit at a time by rotating the media
disk and positioning a single laser
emitter/detector on an arm that moves
from track to track. OROM is radically
different in that it uses no moving
parts. Data is pre-recorded on the
OROM data card in a number of
two-dimensional images or data
patches. There are close to 5,000
patches on the data card, each storing
32Kbytes of data. When the data card
is inserted in the reader, it is aligned
over an array of organic light emitting
diodes (OLEDs). One OLED is assigned
to each data patch on the data card.
To access information the data patch
is illuminated by the OLED assigned to
it. The light is transmitted through the
data patch to create an image of the
data, which is ultimately projected
onto the reader's image sensor. The
sensor and reader's electronics convert
the image to digital data for use in a
computer, game or other supported
device. The total data access time is a
mere 10 milliseconds, the equivalent of
most hard drives, and 10 times faster
than CD-ROMs.
"OROM is an intriguing new approach to
optical storage that is extremely
suitable for mobile computing," said
Mike DeNeffe, director of handheld
products for NEC Computer Systems
Division of Packard Bell NEC. "It has the
potential to dramatically expand the
power and versatility of portable
devices." NEC is a leading worldwide
supplier of notebook and desktop
computer systems, including the
MobilePro series of handheld PCs.
"By enhancing the capabilities of mobile
computing with a high-capacity,
durable and low-cost removable ROM,
OROM promises to extend the ultimate
appeal of highly mobile products." said
Brad Garrison, vice president of Mobile
Computing and Communications for LG
Electronics, USA Inc., a major
consumer electronics manufacturer and
division of LG, a $73 billion global
corporation.
