Abstract

The present invention has an object to provide a recording and reproducing device which can be used both for a cartridge disk (6) and for a cartridge-less disk (3) and reduced in size and weight, and which is capable of aligning a cartridge-less disk (3). A disk holder (14) adapted to set a cartridge disk (6) therein is provided on one and the other sides thereof with positioning means adapted to abut against a cartridge-less disk (3) set in the disk holder (14) to prevent it from moving to the innermost region R of the disk holder (14) and align it in a position corresponding to a rotational driving device (9), said positioning means being in the form of a CD stopper (20) and a step (30) formed in a shutter opener lever (19), thereby supporting and aligning the disk (3).

Dependent claims

A recording and reproducing device for recording information in and reproducing information from a cartridge disk or a cartridge-less disk, comprising:

a disk holder installed on the main body of a device that has a rotational driving device and a recording and reproducing head housed therein, said disk holder being pivotally supported at its innermost region so that a disk set therein can be moved between a recording and reproducing mount position and an exchange position;
and
positioning lever means adapted to abut against a cartridge-less disk set in said disk holder to prevent it from moving to the innermost region of the disk holder and align it in a position corresponding to said rotational driving device and also adapted to abut against a cartridge of a cartridge disk set in the disk holder to move it to a retracted position.

A recording and reproducing device for recording information in and reproducing information from a cartridge disk or a cartridge-less disk, comprising:

a disk holder installed on the main body of the device that has a rotational driving device and a recording and reproducing head housed therein, said disk holder being pivotally supported at its innermost region so that a disk set therein can be moved between a recording and reproducing mount position and an exchange position;
a shutter operating lever provided on one side of the interior of the disk holder, said shutter operating lever being adapted to abut against a shutter of the cartridge disk set in the disk holder so that the insertion of said cartridge causes said shutter operating lever to turn in a direction to open the shutter of said cartridge;
and
positioning lever means provided on one and the other sides of the interior disk holder, said positioning lever means being adapted to abut against a cartridge-less disk set in the disk holder to prevent it from moving to the innermost region of the disk holder and align it in a position corresponding to said rotational driving device;
wherein
said shutter operating lever is integrally formed at its intermediate portion with said positioning lever means.
