The user properly operates an operating apparatus of a system controller 100 and enters an album number and a track number of a track which he wants to erase. The system controller 100 discriminates whether the track corresponding to those numbers has been registered in a play list of an HD recording and reproducing apparatus 300 or not. If it is determined that the track has been registered in the play list, a warning is displayed on a display apparatus of the system controller 100 . After confirming this display, if it is possible to erase the track, the user properly operates the operating apparatus and commits the track erasure. The system controller 100 erases the track whose erasure is desired from the HD recording and reproducing apparatus 300 and erases information corresponding to the erased track from the play list.
