Writing CDs



The Imager Lab now has a Yamaha CDR400 CD recorder that allows you to burn up to 650 Meg of data onto CDs in a variety of handy formats. The CD writer system is based on Ratbert, a Mac IIcx currently located in Imager Dark across from Flip. It is controlled by software called "Adaptec Toast". This program is accompanied by a fairly intuitive and easy-to-follow manual (please keep it near the CD machine!)

Why Would You Want to Use a CD Burner, Anyway?

CDs are cheap, durable and easily accessable ways of recording large amounts of random access data. Some possible uses for the CD-R machine are:

The CD-R machine is also capable of copying audio CDs. You're on your own when it comes to learning how to do this and being responsible for any potential copyright violations.

Preparing Your Files

Before you even touch the CD writer, you should spend some time preparing and organizing the files you wish to store. The process is much easier if all your files are in the same place, so start by creating a new target directory ("my-CD", etc.) and assemble everything you want to write.

It's probably also a good idea to uncompress all your files, for the following reasons:

Pre-assembling your files will give you a handle on the total size of your CD, as well as making the transfer to Ratbert somewhat easier. However, it's not totally necessary.

Choosing a CD Format

Our CD writer supports a wide range of data formats, including MAC data, ISO 9660, Mac/ISO hybrid, Audio CD, CD-i, Enhanced Music CD, and Video CD among others.

This web page concentrates on the two formats we feel will be of most use to lab members:

Reading Your CD Later

On an SGI, slap the CD into a jacket and put it into the CD drive associated with the machine. Your files should be accessable from the directory "/CDROM" on the local machine.
