Toshiba can supply recovery discs - - I know because I bought a set from them three years ago - £15 (UK).
The age of the laptop is critical though - - I think any model more than 10 years old and you'll be out of luck.
For US models:

(scroll down to section "Get Recovery Media").
For European Models: Unfortunately, the page I visited to order my backup media (recovery discs) is not currently responding but that may just be a temporary glitch:
