PURPOSE:To detect easily an absolute address without causing a problem on a space by constituting a titled device so that the absolute address for many disks can be detected by a slit train formed by one line based on a sequence of an M series. CONSTITUTION:A titled device is constituted so that an absolute address for many disks can be detected by a slit train formed by one line based on a sequence of an M series. For instance, at this side of a positioning slit 207 forming part in a tray body 202, a rugged slit 207A determined by the sequence by the M series is formed so as to be superposed, and also so as to be opposed to this slit, six sensors P11-P16 are arranged in one line and provided on a fitting part of a dual sensor 425 in a fitting structure body 420 of a disk search performance mechanism part 400. As for the sequence by the series, a size relation of a decimal number to a prescribed direction gets out of shape, but the same number is not reproduced, therefore, this sequence can be utilized as a sequence for detecting the absolute address. |
