Disk drive using disk tray

A disk drive comprising:

• a disk drive main body provided with a turntable and a head;
• and
• a disk tray provided with a disk mounting part on which a disk is mounted, and configured to be ejectable with respect to the disk drive main body, said disk tray introducing the disk mounted on said disk mounting part into the disk drive main body;
• the disk mounting part of said disk tray comprising:
• a main part having a dimension compatible with the disk, and enabling mounting of the disk in a level position when said disk drive is used in a level position;
• generally crescent shaped extensions produced by extending partially said main part in a radial direction and near corners of the disk tray so as to form corner ear spaces, and said extensions accommodating a portion of said disk mounted on the disk tray only when the disk drive is used in an upright position, said extensions being integral with the main part and formed of the same solid material as the main part;
• and
• fixed tongue parts each extending with a vertical separation from the circumference of each of the crescent shaped extensions and formed as eaves hanging over only the extensions such that peripheral edges of said tongue parts define a circle of a diameter which is compatible with that of the disk accommodated in said main part, whereby the tongue parts support said portion of said disk only when the disk drive is in the upright position and the disk is accommodated in the extensions so that said disk mounted on the disk tray in an upright position is prevented from falling;
• said disk drive main body being provided with, at respective portions facing said disk tray, fixed guide parts for guiding said disk mounted on said disk mounting part in an upright position so as to draw said disk toward said main part of said disk mounting part,
• when said disk is introduced into said disk drive main body, and the positions of said main part, said tongue parts and extensions being fixed with respect to the disk tray throughout entire disk-mounting and disk-ejection operations.

A disk drive comprising:

• a disk drive main body provided with a turntable and a head;
• and
• a disk tray provided with a large-diameter disk mounting part on which a large-diameter disk is mounted and a small-diameter disk mounting part on which a small-diameter disk is mounted, the large-diameter disk mounting part and the small-diameter disk mounting part being concentric with the large-diameter disk mounting part on top of the small-diameter disk mounting part, and configured to be ejectable with respect to the disk drive main body, said disk tray introducing the disk mounted on one of said disk mounting parts into the disk drive main body;
• each of the disk mounting parts of said disk tray comprising:
• a main part having a dimension compatible with the disk, and enabling mounting of the disk in a level position when said disk drive is used in a level position;
• generally crescent shaped extensions produced by extending partially said main part in a radial direction and near corners of the disk tray so as to form corner ear spaces, and said extensions accommodating a portion of said disk mounted on the disk tray only when the disk drive is used in an upright position, said extensions being integral with the main part and formed of the same solid material as the main part;
• and
• fixed tongue parts each extending with a vertical separation from the circumference of each of the crescent shaped extensions and formed as eaves hanging over only the extensions such that peripheral edges of said tongue parts define a circle of a diameter which is compatible with that of the disk accommodated in said main part, whereby the tongue parts support said portion of said disk only when the disk drive is in the upright position and the disk is accommodated in the extensions so that said disk mounted on the disk tray in an upright position is prevented from falling,
• the positions of said main part, said tongue parts and extensions being fixed with respect to the disk tray throughout entire disk-mounting and disk-ejection operations.
