Abstract

A disk drive library has individual disk drives that are each provided with a combination mechanical and electrical connector for interfacing with a library backplane. Each connector has two components. The first component is mounted to the drive and has an electrical contact with a metallic burnished core of highly conductive material that is surrounded by an annular magnet. The mating component is on the backplane and is similarly formed with the opposite pole of a second magnet. When the two components are brought into close proximity, the two contacts attract each other to mate the contact cores, and thus establish an electrical connection. This connection is augmented by a spring mechanism to provide a solid, reliable connection.

Claims

1. A disk drive library, comprising:

a host computer;

a backplane for interfacing with the host computer;

a plurality of backplane connectors interconnected with the backplane, each having at least one spring-biased first interfacing element that is independently movable between extended and retracted positions;

a plurality of disk drive assemblies;

a picker for handling the disk drive assemblies relative to the backplane;

an assembly connector mounted to each of the disk drive assemblies and having at least one second interfacing element for interconnecting with the first interfacing element;

alignment devices for facilitating alignment between the assembly and backplane connectors during make-up;

wherein

each of the assembly and backplane connectors comprises an electrically conductive component and a magnetic component that are coaxial with each other, respectively, the magnetic components circumscribing and being axially movable with their respective first interfacing elements;

wherein

power and control signals are provided between the backplane and the disk drive assembly when the disk drive assembly is coupled to the backplane; and

wherein

the assembly and backplane connectors (a) require zero-insertion force to join the disk drive assembly to the backplane, (b) electrically interface and mechanically couple the disk drive assembly with the backplane, and (c) provide positive retention of the disk drive assembly with the backplane.
