A mechanism for a removable cartridge disk drive data storage system to connect a motor to the hub of a disk inside a removable cartridge including:
- a base having:
- a first side for supporting the removable cartridge;
- and
- a second side having:
- a plurality of positioning members extending from said second side generally perpendicular to said first side;
- a spindle opening defined by said base from said first side to said second side;
- first cam means;
- second cam means spaced from said first cam means;
- and
- a motor assembly including:
- a motor having:
- a spindle adapted for engagement with the hub of the disk in the removable cartridge;
- a motor housing retaining said motor, said motor housing defining:
- a plurality of orifices through which said plurality of positioning members extend, said first and second cam means connecting said motor housing for movement of said motor spindle between a retracted position away from said first side to an extended position through said spindle opening for engagement with the hub of the disk.
A mechanism for a removable cartridge disk drive data storage system to connect a motor to the hub of a disk inside a removable cartridge including:
- a base having:
- a first side for supporting the removable cartridge;
- and
- a second side generally opposite said first side, said base defining:
- a spindle opening;
- first cam means;
- second cam means spaced from said first cam means;
- a motor assembly including:
- a motor having:
- a spindle adapted for engagement with the hub of the disk in the removable cartridge;
- and
- a motor housing retaining said motor;
- and
- means to allow movement of said motor housing generally perpendicular to said first side and to allow slight movements generally parallel to said first side, said first and second cam means connecting said motor housing to said base for causing movement of said motor spindle between a retracted position away from said first side to an extended position through said spindle opening for engagement with the hub of the disk.
A mechanism for a removable cartridge disk drive data storage system to connect a motor to the hub of a disk positioned inside a removable cartridge including:
- a motor assembly including:
- a motor having:
- a spindle adapted for engagement with the hub, said spindle having:
- a axis of rotation;
- and
- a motor housing retaining said motor;
- means to allow restricted generally linear movement of said motor housing between a retracted position with said spindle disengaged from the hub and an extended position with said spindle engaged with the hub while allowing slight movement at right angles to the generally linear movement;
- first cam means;
- and
- second cam means spaced from said first cam means, said first and second cam means being connected to said motor housing to cooperate and move said motor spindle between the retracted position and the extended position.
A mechanism for a removable cartridge disk drive data storage system to magnetically connect a motor to the hub of a disk positioned inside a removable cartridge including:
- a motor assembly including:
- a motor having:
- a spindle adapted for magnetic engagement with the hub, said spindle having:
- a axis of rotation;
- and
- a permanent magnet positioned to magnetically engage the hub;
- and
- a motor housing retaining said motor;
- means to allow linear movement of said motor housing between a retracted position with said spindle disengaged from the hub and an extended position with said spindle engaged with the hub and to allow slight adjusting movements other than the linear movement to assure that said spindle can engage the hub;
- and
- cam means connected to said motor housing to move said motor spindle between the retracted position and the extended position.
