cdrdao command [options] toc-file

cdrdao reads and writes CDs in disc-at-once (DAO) mode. Unlike track-at-once recording, DAO writes the entire disc in a single pass without gaps between tracks, preserving exact sector timing and sub-channel data. This makes it the preferred tool for creating accurate copies of audio CDs where track transitions matter.The tool uses TOC (Table of Contents) files to describe disc layout, which can represent complex disc structures including multi-session discs, mixed-mode discs, and CDs with hidden tracks or non-standard gaps. The TOC format provides more control over disc layout than cue sheets.A typical workflow involves reading a disc with `read-cd` to create a TOC file and binary image, then writing the image back with `write`. The `simulate` command performs a dry run without actually burning.

--device device

CD/DVD device path

Read in raw mode (preserves all data)

Use specific device driver

Set write speed

Source CD device path (for copy command)

Eject disc after operation

Allow writing more data than the medium capacity

Do not close the session after writing, allowing additional sessions

Blanking mode for CD-RW (minimal or full)

read-cd

Read a CD to image and TOC files

Write image to disc

Copy disc to disc

Simulate write operation

Display TOC file contents

Analyze each track and create a TOC file without reading audio/data

Blank a CD-RW disc

Unlock the recorder device after a failed write or simulation

Requires a CD/DVD writer for write operations. Raw read mode may not work with all drives. Copy protection may prevent reading some discs.
