This thread is mixing two different problems. As asked, the right approach depends on the goal: reading files that happen to be on a CD, or performing drive-level operations (eject/lock/burn/read raw sectors). touched on the file side; below are practical, current options for the hardware/control side that go beyond simple file I/O.

For drive/control tasks the JDK does not provide a single cross-platform device API. Common approaches:

  • Call platform command-line tools from Java (quickest). Example utilities: eject on many Unix systems or macOS tools such as drutil. A minimal ProcessBuilder example:

    Process p = new ProcessBuilder("eject", "/dev/cdrom")
    .redirectErrorStream(true)
    .start();
int exit = p.waitFor();

  • Use native APIs from Java by writing JNI code or using JNA to call OS libraries (Windows MCI or DeviceIoControl, Linux ioctl). JNA avoids writing C glue code and is faster to prototype; JNI gives full control for production.

Useful references:

Practical notes: device names, permissions and available commands differ by OS; many operations require elevated rights; burning or raw-sector access typically needs vendor tools or native libraries. For quick tasks, wrap proven command-line tools from Java. For robust cross-platform control, write a small native wrapper (via JNA or JNI) and invoke it from Java, testing per-OS.

What kind of information are you looking for in the CD Rom?

You use File and the various input streams, just like any other file you would access. The CD rom is just another drive, you know.
