Hello Sandy and welcome to Seven Forums.
I have a Vaio VPCEB47GM. One of the problems with burning data to disk is if one of the disks fails to burn properly the rest of the disks become useless. I'm not aware of being able to get an individual disk because the disks are tied to the specific computer that created them. It may be possible to order a complete set of recovery disks from Sony but that could take weeks and you'd have to find out the procedure/price from Sony India.

Instead of using the disks see if you can access the hidden recovery partition instead.
If your model Vaio has the ASSIST button (upper right on keyboard)
1. Turn computer off and then press the ASSIST button. Vaio Care Rescue should launch.
2. Click Start Recovery Wizard > Tools > Start Advanced Recovery Wizard
3. Follow on-screen instructions
If your Vaio does not have the ASSIST button (or if Vaio Care Rescue - above - does not launch)
1. Turn computer on and
immediately start clicking the F10 key (top row of keyboard.) Keep clicking about one click per second until you see the Edit Boot Options screen, then click Enter.
2. Select Start Recovery Wizard > Tools > Start Advanced Recovery Wizard
3. Follow on-screen instructions
