Abstract
Abstract A magnetic disk drive has a drive motor mounted on a yoke which rotatable about a pivot in the drive. A bezel member mounted on the end of the yoke normally closes the opening the disk drive through which a cartridge is inserted. As this bezel member is moved out of the cartridge, the motor is moved out of the position in which it engages the disk and when the bezel member is closed, the motor moves into the engagement position. The motor is mounted on the yoke with a movable connection so that it is guided in a linear movement into engagement with the motor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
A magnetic disk drive for writing and reading data to and from a magnetic disk contained in a cartridge which is inserted through an opening into said disk drive comprising: a yoke rotatable about a pivot in said disk drive; a bezel member mounted on the end of said yoke to normally close said opening and; a motor having a spindle for engaging said magnetic disk to rotate it, said motor being mounted on said yoke so that rotation about said pivot moves said bezel member out of said opening and moves said motor spindle out of engagement with said disk and opposite rotation of said yoke moves said bezel member into said opening and moves said motor spindle into engagement with said disk.
Claim 2
Dependent Claim
124 words
A magnetic disk drive for writing and reading data to and from a magnetic disk contained in a cartridge which is inserted through an opening into said disk drive comprising: a yoke rotatable about a pivot in said disk drive; a bezel member mounted on the end of said yoke to normally close said opening and; a motor having a spindle for engaging said magnetic disk to rotate it, said motor being mounted on said yoke so that rotation about said pivot moves said bezel member out of said opening and moves said motor spindle out of engagement with said disk and opposite rotation of said yoke moves said bezel member into said opening and moves said motor spindle into engagement with said disk.
Claim 3
Dependent Claim
56 words
The magnetic disk drive recited in claim 1 wherein said disk drive has a base on which said yoke is pivoted; a movable connection between said motor and said yoke; and reference surfaces on said base for guiding said motor, by movement of said movable connection, into proximity with said magnetic disk in a linear movement.
Claim 4
Dependent Claim
28 words
The magnetic disk drive recited in claim 2 wherein said motor has a flange and wherein said movable connection includes suspension springs between said flange and said yoke.
Claim 5
Dependent Claim
43 words
The magnetic disk recited in claim 1 wherein said flexible disk is enclosed in a rigid cartridge having an opening in one side thereof for engagement of said magnetic head and said motor with said disk from the same side of said disk.
Claim 6
Dependent Claim
161 words
A magnetic disk drive for reading and writing data to and from a magnetic disk contained in a cartridge which is inserted through an opening into said disk drive comprising: a yoke rotatable about a pivot in said disk drive; a bezel member mounted on the end of said yoke to normally close said opening; a motor having a spindle for engaging said magnetic disk to rotate it, said motor being mounted on said yoke so that rotation about said pivot moves said bezel member out of said opening and moves said motor spindle out of engagement with said disk and opposite rotation of said yoke moves said bezel member into said opening and moves said motor spindle into engagement with said disk; a base on which said yoke is pivoted; a movable connection between said motor and said yoke; means for guiding said motor, by movement of said movable connection, into proximity with said magnetic disk in a linear movement.
Claim 7
Dependent Claim
161 words
A magnetic disk drive for reading and writing data to and from a magnetic disk contained in a cartridge which is inserted through an opening into said disk drive comprising: a yoke rotatable about a pivot in said disk drive; a bezel member mounted on the end of said yoke to normally close said opening; a motor having a spindle for engaging said magnetic disk to rotate it, said motor being mounted on said yoke so that rotation about said pivot moves said bezel member out of said opening and moves said motor spindle out of engagement with said disk and opposite rotation of said yoke moves said bezel member into said opening and moves said motor spindle into engagement with said disk; a base on which said yoke is pivoted; a movable connection between said motor and said yoke; means for guiding said motor, by movement of said movable connection, into proximity with said magnetic disk in a linear movement.
