A 4x or 8x DVD burner is a great solution.
If it must be on CDR, consider using a fractal
or wavelet compression format.

Both Genuine Fractals and MrSid have lossless capability.
A Genuine Fractals STN file will allow a lossless compression
ratio of approximately 2:1 and visually-lossless at 5:1.

I have created visually-lossless files using MrSid with
a ratio of 20:1. Only a trained eye could detect a difference.
