Seems like somebody missed a point here about CD-R (CD-Recordable)
technology and how it works.

For the "final" version, the time frame would be weeks.
For pre-release versions, though, a single CD can be written from
the desktop using a CD-R device. Current price of CD-R devices
is $2500 +/- $500.

This approach is for a production run of CDs from a master.
Seems like EPICS is a pretty good application for CD-R since it is
written directly onto the CD without an intermediate mold and
the final number of pieces is small.

4) Alternative to exabyte tape is a CD.
Usual advantages/disadvantages apply.
