I have a record cabinet that has the door tracks dadoed in. The frames are
wider (thicker) than the panels so they fill in the gap between the doors.

It may be a little tricky to do this with a router because of potential
tear-out. If you have a dado cutter, you may have better success.

I am going to put sliding doors on a cabinet. Is there any reason not to
simply rout the tracks into the cabinet, rather than putting tracks in?
I don't think I have ever seen it done that way, but it should be rather
nices.
Thanks.
