  • Patent number: 6271989
    Abstract: A method of inserting a removable data cartridge into a disk drive utilizes a cartridge having a registration contour adapted for alignment with a registration member of the disk drive. The registration contour slides along the registration member during insertion. The cartridge has an interlocking recess adapted to interface with an ejector pin of the disk drive, and a door biased to a closed position, where the door has a tab engaging the disk drive and holding the housing door open while the cartridge is in the inserted position. The cartridge is ejected by releasing the ejector pin from the interlocking recess and pushing the cartridge with the ejector pin.

  • Patent number: 5822162
    Abstract: A cartridge 52 adapted for being inserted into a disk drive 50 includes a housing 70 which contains a disk 256 mounted for rotation and an interlocking device 90 defined in the housing 70 and adapted for automatically lockingly positioning the cartridge 52 in the disk drive 50 as the cartridge 52 comes to a final position relative to the disk drive 50. The interlocking device 90 includes an element 90 which is defined in the cartridge housing 70 in the direction which is substantially across the direction of insertion of the cartridge 82 into the drive 50. The interlocking device 90 includes a recess 90 for lockingly positioning the cartridge 52 which recess 90 includes an opening 360 disposed through the front edge 98 of the cartridge 52 and which is directed therefrom in a direction which is substantially across the direction of insertion of the cartridge 52 into the drive 50.

  • Patent number: 5535072
    Abstract: A disk drive 50 for receiving a removable cartridge 52 containing a disk 256 for storing data. The disk drive 50 includes a spindle motor 102 for engaging and causing the disk 256 of the cartridge 52 to spin at an appropriate speed and a mechanism 168 for mounting the spindle motor 102 to the disk drive 50 so that the spindle 102 motor is movable from a first position out of engagement with the disk 256 to a second position operably engaged with the disk 256. The spindle motor 102 can thus move in a plane which is not coplaner with the cartridge receiving plane. The disk drive further includes an ejecting mechanism 106 for engaging and lockingly holding the cartridge 52 in place in the cartridge receiver 60 and for ejecting the cartridge from the cartridge receiver 60.
