Recordable DVD & SONY VAIO PCG-GRV516G

Hello,
does anyone know if those DVD’s (PIoneer DVR-K 12D Slim LIne and Toshiba SD-R6012) are compatabile with SONY VAIO PCG-GRV516G notebook?
Has anyone any experience with them or is there any other suggestions as I would like to buy a compatabile one.

Thanks,
Cobek
