"The number of discs in the recovery-disc set depends on your
computer model
(typically 1–3 DVD discs). The *Recovery Disc Creator* program will
tell you the
specific number of blank discs needed to make the set."
That would correspond to making an image of the recovery partition
on the hard drive. (On my Acer computer, this would be a four disc
set, three discs for Windows 7, and an additional disc claiming to
be drivers.)
You could try going to the program launch thing and typing "recovery"
and see what pops up. Or browse C: and the Program Files to find
something named like that.
If the computer has already made one set of recovery media, it
may refuse to make a second set. For example, if the computer
is used, the first owner makes a set, the Recovery Disc Creator
keeps track of whether it made a set or not. Only one set is
supposed to be made, per machine.
If that were to happen, I'd just use something like Macrium Reflect Free,
and just image the entire drive. That way, if you need to put the
recovery partition back on the computer, you have a means to do so.

You can make a fifth disc, on the menu for "System Image". That
disc would be 200MB in size, and fits on a CD. The other discs
might well require blank DVDs. The purpose of a "System Image"
disc, is for restoring from the Windows 7 backup software. The
disc also has a recovery console, a "DOS prompt" you can boot
to, to use tools such as bootrec, bootsect, bcdedit, chkdsk,
diskpart and so on. As well as dos-like "dir" and friends.
That's for when the computer is broken, and the built-in boot
repair capabilities of Windows 7 no longer work. Your computer
won't come with a "real" installer DVD, but you can download
one of those off the Internet (~3.3GB) and the installer DVD
will also boot to the recovery console. So even if your
computer is completely broken, you can still download something
that can be used to boot the computer.
I would not store the recovery information solely on DVDs or
on a USB stick. Make images of the media as soon as you've finished
creating them. You should have two copies. If your DVDs develop
"bit-rot", the images you make of the DVDs can be used to make
more DVDs at a later date.
