Here's what I recommend. |

|

1) Use ddrescue to read as many data blocks as you can off the CD. |

12 |
|
13 |
ddrescue will retry failing blocks and then skip over them. You |
14 |
can rerun ddrescue to try to fill in missing blocks. dd or cat |
15 |
will generally just stop when it hits the first bad block. |
16 |
|

I would do something like: |
18 |
|
19 |
a) Run several passes of ddrescue using a few different optical |
20 |
drives. |
21 |
|
22 |
b) Polish the CD. |
23 |
|
24 |
c) Repeat until you stop getting new data off the CD. |
25 |
|
26 |
|
27 |
2) Use something like photorec to try to scavange any reconizable |
28 |
JPEGs (or other file types as desired) from the data image file |
29 |
you created with ddrescue. |

IIRC, there are ebuilds for ddrescue, photorec, and testdisk. |
