#CD-ROM s'ware develop?
6 messages in this thread
I'm preparing to go to market with a new Windows application. It is a system
for managing, displaying and distributing information (text, graphic etc) and
makes extensive use of pick lists, hypertext linking and similar. I am
interested in the possibility of either developing CD-ROM titles using this
software, or marketing the software to developers.
My question is, how does one test things like response times for a product
which will run from a CD-ROM. I know how to optimize code for a hard disk
environment, but not how to optimize for an environment where the disk is
being read at maybe 300 ms versus the <12 I get on my system's hard drives –
let alone the slow data throughput of a CDROM drive. How does one get around
these problems during software development?
Any input, or pointers to information sources, very gratefully received!

Ric,
You can either buy a cdrom emulator (software) or you can make a test cdrom
(one-off). Depending on how many times you have to repeat the cycle, making
the one-off could be more practical, since that would cost probably less than
$300 if you have a service bureau (like mine) do it. The emulator software,
depending on whose you buy, is usually part of a premasterming systems and can
cost thousands.

Thanks for the info. I'll discuss it with my partners and try to decide which
way to jump.

Richard,
After using a CD simulator or your best "seat-of-the-pants" guesstimate, you
might consider having the premastering done on a Sony CDW-900E or its
equivalent. This professional CD Writer produces a disc that is equivalent to
a manufacturer's stack check disc for the price of a consumer one-off disc.
We call these QuickOne(tm) discs. Once you have tested it, our disc
manufacturer uses that disc, without reformatting or re-encoding, to clone a
master. A QuickOne disc complies in all respects with the Red Book, Yellow Book
and Green Book standards, and may therefore be used with any commercially
available CD player, CD-ROM drive or CD-I player. These discs are functionally
equivalent including performance characteristics, to that of a mastered CD.
If you decide to support multiple platforms, it is the only that I know of to
accurately test every platform prior to mastering.
I hope that helped… sorry if I had my marketing beanie on too tight. 🙂

Thanks for the info. I don't mind your wearing the marketing beanie at all –
just now I'm trying to learn everything I can about the options.
