초록 ▼

Apparatus for hot removal from/insertion to a connection bus of a non-removable-media magnetic recording unit, comprising a plurality of electromagnetic switches for isolation of the signal terminals of the unit from the bus, thereby preventing noise injection into the bus; control and timing circuits for deenergization of the unit only after opening of the switches and for enabling removal of the unit only after deenergization and circuits for imparting to the signal terminals of the unit a bias voltage intermediate or close to the electrical signal levels present on the bus, the insertion occurring by closing the switches when the unit is already powered and the terminals are biased so as to minimize the amplitude of the noise injected onto the bus.

대표청구항 ▼

Apparatus for hot removal from/insertion to a connection bus of a non-removable media magnetic recording unit, a plurality of magnetic recording units being connected to said connection bus through connectors, comprising: a housing having a first connector with a first set of housing terminals connected to said bus, a second set of housing terminals connected to voltage sources and a third set of housing terminals selectively connected together by straps, a container removably inserted in said housing and having a second connector for coupling with said first connector, said second connector having a first, a second and a third set of container terminals corresponding to the housing sets respectively for coupling with said first, second and third set of terminals of said first connector, said container containing a) a recording unit having a first set of unit terminals intended for connection to said bus, a second set of unit terminals intended for connection to voltage source and a third set of unit terminals for unit identification by means of straps selectively connecting said unit identification terminals in said third unit terminal set, and b) direct electrical connection of said third unit terminal set to said third container terminal set of said second connector, means in said container for electrically connecting said first terminal set of said unit to said first set of housing terminals, through said second connector of said container and a set of switches, each of said switches controlling the electrical connection of a terminal in said first set of unit terminals to a terminal in said first set of container terminals. electrical bias means for said first set of unit terminals, operative to apply a predetermined voltage to said first set of unit terminals when said container is inserted in said housing and said recording unit is unpowered, and control and timing means in said container, operative when said container is housed in said housing, for activation of said recording unit by first connecting said second set of unit terminals to at least a powering voltage source, through said second set of container terminals and said second set of housing terminals and by second closing said plurality of switches, and for deactivation of said unit by first opening said plurality of switches and by second disconnecting said second set of unit terminals from at least one of said voltage sources, for subsequent removal of said container from said housing.
