Abstract
An apparatus and associated method is provided for injecting a processing fluid in a device that operably rotates a disc stack. A fluid injector has a nozzle defining an outlet sized to longitudinally span the disc stack to operably direct the processing fluid toward the disc stack. The nozzle also has a flow rate feature that operably directs a first flow rate of the processing fluid from the nozzle into a space adjacent a storage surface of a first disc of the disc stack and that directs a substantially different second flow rate of the processing fluid from the nozzle into another space adjacent a storage surface of a second disc of the disc stack.
Claims15
A fluid injector in a device that rotates a disc stack, the fluid injector comprising a nozzle defining a plurality of outlets that direct processing fluid from the nozzle to the disc stack, at least some of the plurality of outlets are each aligned with a space between adjacent discs of the disc stack, wherein a first outlet of the plurality is sized larger than a second outlet of the plurality to provide a substantially different flow rate from the first outlet compared to that of the second outlet.
A method comprising:
- rotating a disc stack;
- supplying a processing fluid to a fluid injector having a nozzle defining a plurality of outlets that direct the processing fluid from the to the disc stack, wherein a first outlet of the plurality is sized larger than a second outlet of the plurality to provide a substantially different flow rate from the first outlet compared to that of the second outlet;
- and
- sensing a temperature within the disc stack and responsively regulating a flow rate with which the processing fluid enters the nozzle.
A data writing device, comprising:
- a spindle operably supporting a disc stack in a data transfer relationship with a plurality of data transfer members;
- and
- means for controlling part-to-part positional variation among different data transfer members of the plurality in relation to respective storage locations of the disc stack by substantially equalizing environmental temperatures in spaces adjacent the discs in the disc stack where the data transfer members reside in response to thermal excitation created by operating the writing device that heats the spaces at different rates.
