Claim 1

Independent Claim 413 words

In a disk drive information storage system, (a) a complete disk drive unit requiring electrical power for effecting disk rotation, said complete disk drive unit being comprised of rotary disk information storage means for storing information, disk rotary drive means for effecting disk rotation, and information transducer means for effecting disk scanning, (b) disk drive carrier means for carrying said complete disk drive unit and having said complete disk drive unit carried therewith, and having electrical connector means for providing power and signal electrical transmission path means which are connected with said complete disk drive unit for the transmission of power for effecting disk rotation and for the transmission of control and data signals, said connector means being secured in fixed relation with said complete disk drive unit, and (c) a receiving unit having electrical connector means secured therewith and arranged for releasably mating with the electrical connector means of said disk drive carrier means and providing power and signal electrical transmission path means such that all required electrical transmission paths are completed from the receiving unit to the complete disk drive unit when the electrical connector means of said receiving unit is releasably mated with the electrical connector means of said disk drive carrier means, (d) said disk drive carrier means and said receiving unit having a final assembled relationship in which the electrical connector means of the disk drive carrier means releasably mates with the electrical connector means of the receiving unit, and in which power for effecting disk rotation and control and data signals can be transmitted between the receiving unit and the complete disk drive unit, and having cooperating means for releasably retaining said disk drive carrier means in said final assembled relationship with said receiving unit and for accommodating bodily removal of the complete disk drive unit in its entirety from the receiving unit by removal of said disk drive carrier means from said final assembled relationship after power has been removed from the disk drive unit and the disk drive unit has been allowed to spin down, (e) said cooperating means of said disk drive carrier means and said receiving unit serving to so constrain said electrical connector means of said disk drive carrier means while said disk drive carrier means is being inserted into said final assembled relationship with said receiving unit as to effect mating of said electrical connector means of said disk drive carrier means with said electrical connector means of said receiving unit.

Claim 2

Dependent Claim 413 words

In a disk drive information storage system, (a) a complete disk drive unit requiring electrical power for effecting disk rotation, said complete disk drive unit being comprised of rotary disk information storage means for storing information, disk rotary drive means for effecting disk rotation, and information transducer means for effecting disk scanning, (b) disk drive carrier means for carrying said complete disk drive unit and having said complete disk drive unit carried therewith, and having electrical connector means for providing power and signal electrical transmission path means which are connected with said complete disk drive unit for the transmission of power for effecting disk rotation and for the transmission of control and data signals, said connector means being secured in fixed relation with said complete disk drive unit, and (c) a receiving unit having electrical connector means secured therewith and arranged for releasably mating with the electrical connector means of said disk drive carrier means and providing power and signal electrical transmission path means such that all required electrical transmission paths are completed from the receiving unit to the complete disk drive unit when the electrical connector means of said receiving unit is releasably mated with the electrical connector means of said disk drive carrier means, (d) said disk drive carrier means and said receiving unit having a final assembled relationship in which the electrical connector means of the disk drive carrier means releasably mates with the electrical connector means of the receiving unit, and in which power for effecting disk rotation and control and data signals can be transmitted between the receiving unit and the complete disk drive unit, and having cooperating means for releasably retaining said disk drive carrier means in said final assembled relationship with said receiving unit and for accommodating bodily removal of the complete disk drive unit in its entirety from the receiving unit by removal of said disk drive carrier means from said final assembled relationship after power has been removed from the disk drive unit and the disk drive unit has been allowed to spin down, (e) said cooperating means of said disk drive carrier means and said receiving unit serving to so constrain said electrical connector means of said disk drive carrier means while said disk drive carrier means is being inserted into said final assembled relationship with said receiving unit as to effect mating of said electrical connector means of said disk drive carrier means with said electrical connector means of said receiving unit.

Claim 3

Dependent Claim 88 words

In a disk drive information storage system according to claim 1, said disk drive carrier means having a carrier handle disposed for convenient carrying of the carrier means and the complete disk drive unit carried therewith, and said cooperating means providing for interengagement of the disk drive carrier means with the receiving unit solely by manipulation of said carrier means, and thereafter guiding said carrier means and the complete disk drive unit carried therewith into said final assembled relationship as manual force is applied to said carrier handle.

Claim 4

Dependent Claim 87 words

In a disk drive information storage system according to claim 1, said cooperating means guiding said carrier means together with the complete disk drive unit carried therewith such that the electrical connector means secured in fixed relation with the carrier means reliably mates with the electrical connector means secured with the receiving unit as the carrier means together with the complete disk drive unit carried therewith is impelled solely by manual force applied directly to said carrier means into said final assembled relationship with said receiving unit.

Claim 5

Dependent Claim 49 words

In a disk drive information storage system according to claim 3, said receiving unit having latching means engageable with said disk drive carrier means as the carrier means is inserted into said final assembled relationship with said receiving unit solely by manual force applied directly to said carrier means.

Claim 6

Dependent Claim 80 words

In a disk drive information storage system according to claim 4, said disk drive carrier means having a carrier handle disposed for convenient carrying of the carrier means and the complete disk drive unit carried thereby, and said latching means being releasable in response to manual removal force applied to said carrier handle so as to accommodate removal of the carrier means together with the complete disk drive unit from the receiving unit solely by manipulation of said carrier handle.

Claim 7

Dependent Claim 115 words

In a disk drive information storage system according to claim 3, said disk drive carrier means having mounting lug means providing for interengagement of the carrier means with the receiving unit, said receiving unit having retainer means for receiving said lug means with the carrier means in a tilted orientation relative to said receiving unit while accommodating a pivotal movement of the carrier means about said retaining means into said fully assembled relationship with said receiving unit, said retainer means providing part of said cooperating means for guiding the carrier means and being constructed such that the electrical connector means mate with each other as the carrier means is pivoted into the fully assembled relationship.

Claim 8

Dependent Claim 85 words

In a disk drive information storage system according to claim 6, said lug means providing lug surfaces and said retainer means providing open slots for receiving said lug means and having bearing surfaces at interior ends of said slots such that with the lug means manually pressed into said slots in the tilted orientation, the pivotal movement of the carrier means is constrained and guided by the rotational contact of the lug surfaces of the lug means with the bearing surfaces of the retainer means.
