Disk cartridge

A disk cartridge accommodating a disk in a recording/reproducing apparatus comprising a pick-up, the disk cartridge comprising:

• a case receiving the disk and having openings to enable the pick-up access of the disk;
• and
• a shutter opening/closing the openings,
• wherein the case comprises upper and lower portions, each comprising a first width W1 and a third width W3 being different from each other so that the openings having a second width W2 deviate a predetermined distance from a middle position of the case toward one side of the upper and lower portions, respectively, and the shutter moves toward a direction to expose the openings and allow the pick-up to access the disk, where a difference between the first width W1 and the third width W3 compensate for the deviation of the openings.

An apparatus, comprising:

• a disk cartridge accommodating a disk and comprising:
• a case receiving the disk, wherein openings deviating a predetermined distance from a middle position of the case toward one side, and
• a shutter opening/closing the openings;
• and
• an adapter supporting the cartridge between first and second side walls, wherein a difference between widths of the first and second side walls compensate for the deviation of the openings.

A disk cartridge accommodating a disk, comprising:

• a case comprising upper and lower portions forming a space to receive the disk, the case having openings and spindle receiving holes;
• and
• a shutter selectively opening/closing the openings and spindle receiving holes,
• wherein upper and lower portions, each comprises a first width W1 and a third width W3 being different from each other so that the openings having a second width W2 deviate a distance toward one side of the upper and lower portions, respectively, from corresponding center points of the spindle receiving holes, where a difference between the first width W1 and the third width W3 compensate for the deviation of the openings.

An apparatus, comprising:

• a disk cartridge accommodating a disk comprising:
• a case receiving the disk and having openings formed to deviate a predetermined distance from a middle position of the case toward one side, and
• a shutter opening/closing the openings;
• an opening lever;
• and
• an adapter comprising first and second side walls supporting the disk cartridge, the adapter comprising:
• an auxiliary shutter joined to the shutter of the disk cartridge and slid by the opening lever to open and close the shutter, wherein a difference between widths of the first and second side walls compensate for the deviation of the openings.

An adapter receiving a disk cartridge comprising a case having openings deviating a predetermined distance from a middle position of the case toward one side and a shutter opening/closing the openings, the adapter comprising:

• a first side wall having a width L1;
• a second side wall having a width L2, wherein the disk cartridge is supported between the first and second side walls;
• and
• an auxiliary shutter joined to the shutter of the disk cartridge and slid by an opening lever to open and close the shutter, wherein a difference between widths L1 and L2 compensate for the deviation of the openings.
