Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Kind of a trick question. Most modern linux view storage by using scsi access. That doesn't mean the real physical access is scsi. For that you'd need a scsi adapter and a scsi optical drive. That is not unheard of but kind of rare.
I suspect you have some sata drive or even ide that is simply being accessed by linux as a scsi device.

DESCRIPTION
cdcd allows control of a CD player either directly off of the command
line or in its own interactive query mode. Invoking cdcd without a
command will cause cdcd to enter query mode. Invoking cdcd with a com-
mand will cause cdcd to execute that command and then terminate when it
is finished.
OPTIONS
--device DEVICE
-d DEVICE
Use DEVICE as the CD device. DEVICE is the device special file
name of the CD-ROM device. Do not use a Linux SCSI Generic
device.
Actually, I believe that's really saying not to use generic scsi device addresses, the kind that use major and minor numbers. Only use the standard /dev/sr* style device entries.
It used to be common for some cd-rom drive controlling programs to require direct device addressing, but that's rarely needed any more.

Reason: bit of rewording

I still use cdrecord thus: cdrecord <some_parameters> dev=1001,0,0 <some_other_parameters>. If I address the device as, say, /dev/hdc, then it complains, although accepts it anyways. Is this what you mean? Although in cdrecord syntax 1001,0,0 are scsibus, target, lun.
