DVD Forum to Firm Up 4.7GB DVD-R Standard

October 15, 1997 (TOKYO) -- Working Group 6 of the
DVD Forum decided to firm up a DVD-R standard for disks
with a storage capacity of 4.7GB per side during a meeting held in late
September 1997.

The forum includes companies in the disk business that participate in the
process of deliberations or propose a standard.

The group will proceed with full-scale deliberations on the standard
after a DVD Forum open meeting slated for late October.

The meetings for standardization will be held once a month and last
from six months to a year to deliberate and evaluate proposals from the
companies concerned. The group will finalize the DVD-R format with a
storage capacity of 4.7GB per side by next spring at the earliest.

Several companies proposed their formats to Working Group 6 in
addition to Matsushita Electric Industrial Co., Ltd. and Pioneer
Electronic Corp., which already had disclosed their specifications as
candidates for the standard.

The write-once optical disk format proposed by Pioneer attained jitters
of about 8 percent at a tilt angle of zero degrees and about 20 percent
at tilt angles of -0.8 degrees and +0.8 degrees, thanks to a newly
developed organic pigment and output control in writing.

The company official said that it was close to the specifications required
by the DVD-R format, with a storage capacity of 3.9GB per side: the
jitters less than 9 percent at a zero tilt angle and jitters of less than 15
percent at tilt angles of -0.8 degrees and +0.8 degrees.
