If you want to have a DVD/RW on your laptop you will probably need to buy an external one that plugs into your USB port.
I would think any external USB drive would be compatible with a laptop. There are loads of makes, so you need to search sites like dabs.com and so on.
Something like this (I am not saying this is the best, just an example)

Note the company who made your laptop may sell one that goes inside your laptop case to replace the existing drive, but it may be expensive.
I would go down the external USB route.
