Performing a clean install of OS X Mountain Lion erases all the data on the target disk. It contains a bootable system with utilities for performing basic disk repair, as well as the ability to reinstall the OS if necessary. This is a hidden partition created by the Mountain Lion installer.

650MB of free space for the Recovery HD partition.

A minimum volume size of at least 60GB provides sufficient room for the OS, user data, apps, and some free space. You can squeeze Mountain Lion onto a smaller drive, but there won't be much space left for user data and applications. The target volume must be at least 8GB in size.

If the disk is unreadable then recovery disk will not work - and when you put in a new blank disk it won't be on that one either, so the recovery procedure outlined will not work here.
