Can't create all recovery disc

Hello,
I had tried many times to create all 4 discs at once or separately(single\single). I just able to create disc # 01 and while preparing other, System just run but it is not giving me conformation that CD is ready only gives me creating disc please wait. I waited more than 8 hrs also still result was same. Is disc # 01 is enough or I need all disc to recover my system? My Machine is Satellite L500-12T. If I need to create all disc, how can I create them now? Or If I need to bye the recovery disc, to whom can I address? I am waiting for easy answer.

Thank you.
