Unless you manually resize the window to full-screen (keeping the menu bar visible) by dragging a corner, I don't think you can prevent the menu bar from disappearing; it's a "feature" of full-screen mode.

Even if the menu bar disappears, moving the cursor to where it was causes it to pop down. There are also apps that assist with resizing and repositioning windows that could keep the menu bar visible.
