2. Description of the Related Art As one of conventional recording medium reproducing apparatuses,
There is a bank type CD changer type CD reproducing apparatus which can store a plurality of CDs in each CD storing area of a storing section and pull out and play them at any time. In this CD reproducing apparatus, each CD stored in each CD storage area of the storage section
When a disc number corresponding to an arbitrary disc among the discs and a track number (hereinafter referred to as TNO) to be reproduced on the disc are designated for different discs, a normal program reproduction mode in which the discs are continuously reproduced in a designated order, and a CD disc. There is a special program reproduction mode in which only one TNO among the TNOs is designated, and only the same TNO as the designated TNO of each disc in the storage section is automatically programmed and continuously reproduced. In particular, it is common for users to exchange and reproduce single CDs and record only the first song of each single CD on a tape, MD, or the like, and it is convenient to use this special program reproduction mode. However, these conventional CD reproducing devices clear all the information programmed up to now if any one of the CDs is ejected, so that the first tune of all the stored single CDs is deleted. After recording, it was necessary to reprogram a different single CD. In addition, the inventor of the present application has invented a CD that excludes only the program information related to the ejected CD, regardless of the ejected CD.

FIG. 4 is a flowchart for explaining an operation procedure in the special program reproduction mode. First, in the special program playback mode, it is determined in step S11 whether or not the open keys corresponding to the disk numbers 1 to n (n is an integer) have been pressed.
If not, the process returns to step S11. Step S
At 12, the program of the open disk pulled out from the storage section is cleared, and then the process proceeds to step S13.
In step S13, the program tunes of the other discs in the next and subsequent discs are packed in the cleared and free order position on the program. Next, the process proceeds to step S14, where it is determined whether the close key has been pressed. If yes, the process proceeds to step S15, and if no, the process returns to step S14. In step S15, the open disk is closed, stored in the storage area of the storage section, and the operation is completed.
