Patent 7467394 was granted and assigned to Pioneer Corporation on December, 2008 by the United States Patent and Trademark Office.
The tray 30, which can mount both of a cartridge type recording medium and a bare-disc type recording medium, includes a placing surface 31 having a detection hole 34 for detecting information of the recording medium; a rising portion 32 formed so as to rise from the placing surface 31 at a front side end. The rising portion 32 has a disc holder 35 rotatably provided for positioning the bare-disc type recording medium. Hence, the disc holder 35 can be moved to an accommodation position A for being displaced not to cover the detection hole 34 in the placing surface 31. Accordingly, an area on the placing surface 31, in which detection portions such as the detection hole 34 are formed becomes wider, so that the detection portions such as the detection hole 34 can be sufficiently formed as well as a space for providing the detection portions corresponding to a cartridge containing a variety of information can be sufficiently obtained.
