A device may be or include a cartridge configured to receive a head gimbal assembly (HGA) of a storage device and electrically connect the HGA to a HGA testing device. The cartridge may include a pre-amplifier configured to be electrically connected with corresponding electrical traces of the HGA and to the HGA testing device; a plurality of probe pins electrically connected to the pre-amplifier and configured to be electrically connected to corresponding electrical traces of the HGA; and a clamper including a dielectric layer and configured to selectively assume an open or closed configuration. In the closed configuration, the plurality of probe pins is electrically connected to corresponding ones of the plurality of electrical traces of the HGA. The clamper, in combination with at least some of the probe pins, forms an electrical filter configured to at least condition signals to and from the pre-amplifier and the HGA.

Systems and methods for improving loading and unloading of a read or write head onto and off of a disk medium. Particular embodiments may assist in loading a read or write head to, or unloading a read or write head from, a load location over a surface of a disk medium in such a manner that damage to the surface of the disk medium (e.g., load location) is either prevented or minimized. The prevention or reduction of damage may be achieved by ensuring that a read or write head has sufficient clearance over the surface of a disk medium as the read or write head moves over the surface (e.g., as the head moves parallel to the surface) during a head loading or unloading process.
