- One way this is done is to use a special disk drive to write the disk
- and write data at a higher rate than the typical Macintosh can write
- it. However, the typical Mac drive is capable of reading this faster
- written data. Thus, you can read it all day long, but you need the
- special drive to write it.

- I do not know if this is still done or not.
