The HP recovery disc will restore your machine to factory condition; which means any personal data, settings, or programs you may have installed after you bought your computer will not be contained on those recovery discs.
I recommend generating a separate backup disc with all your personal data on it; you should make a backup disc like that at least once a month, and back up any critical data even more often.
You should also make sure you have copies of that back-up data in separate locations (say, a copy at the office as well as at home), in case something catastrophic occurs at the locatin of your primary backup.
