Point: With modern hardware a "raw disc" can be multiple physical discs which the Operating System sees as one physical disc.
Some research ideas:
Consider the case of a virgin disc. There are no filesystems unless your software creates a filesystem. You can write or read whatever you like within the physical dimensions of the disc.
The very basic filesystems follow the pattern of the original IBM tape format VOL1 HDR1.
For research purposes it is worth a look at CAFS (Content Addressable File Store). That's the way to use a raw disc! It's so much better than "Binary Tree", "Hash Random" or "Index Sequential" file systems when dealing with disorganised data.

Is there any system call available in AIX to read the size of raw disk?
If I use the command "lspv -L",it only gives size of PVs on which file system is there. I need to extract the size raw disk i.e. file system is not there on the disk.

NAME
cdde - Compact Disc Detect & Execute
SYNOPSIS
cdde [-c filename] [-rbvVh]
DESCRIPTION
cdde is a program that detects when a cdrom drive on your system has had a disc inserted.
When it finds a disc inserted in the drive it will attempt to determine the type of the disc, and execute a specified command.
This means you can put in a dvd and your favorite dvd software will start, or put in a data cd and it will be automatically mounted for
you.
Right now cdde can detect the following types of discs:
* audio cd
* data cd
* dvd
* mixed audio/data cd
* vcd
* svcd
* blank cdr/dvdr
For now the dvd checking is just a bit of magic that checks to see if there's a "video_ts" directory on the disc. Same goes for the vcd
checking: it just looks for a "vcd" directory on the disc.
cdde reads its configuration from "~/.cdde.xml" unless otherwise specified on the command line.
OPTIONS
-r, --run
Run commands on disc already in drive when is started.
-b, --batch
Batch mode: check all drives once then exit. (implies -r)
-c, --config <filename>
Use the config file <filename>. (Default is ~/.cdde.xml)
-v, --verbose
Print out lots of information.
-V, --version
Print out version information.
-h, --help
Print Display this help and exit.
FILES
~/.cdde.xml
