Abstract: Devices and methods are disclosed for a lubricant station for applying lubricant to storage disk platters. The lubricant station includes a tub for holding lubricant and a caddy disposed in the tub, with the storage disk platters placed in the caddy. The caddy includes a mandrel configured to raise and lower the storage disk platters into the tub. The caddy also includes rotatable shafts configured to hold the storage disk platter. The caddy also includes a drive mechanism for rotating the rotatable shafts. The lubricant station also includes control circuitry configured to lower the storage disk platters onto the rotatable shafts of the caddy, rotate the rotatable shafts and the storage disk platters, and remove the storage disk platters from the tub.

Abstract: A disk hub is configured to retain a magnetic recording medium including an annulus shape and a layer configured for magnetic recording. The disk hub includes a base plate portion for supporting an inner diameter area of the magnetic recording medium and a stem portion on the base plate portion. The base plate portion is configured to support the inner diameter area of the magnetic recording medium. The stem portion includes a first section with a frustoconical shape and a second section extending between the first section and the base plate portion. A circumference of the second section increases in a direction away from the base plate portion, and a circumference of the first section decreases in the direction away from the base plate portion. The disk hub includes an electrostatic dissipative material. The electrostatic dissipative material can be infused with carbon nanotubes.
