摘要： A battery pack has series-parallel connected battery cells. An inrush current limiting circuit has current limiting devices and a current limiting tracking means limits inrush current from shorted battery cells. Each current limiting tracking means is coupled to the current limiting devices such that they limit an inrush current from parallel neighbor battery cells when one battery cell on the column shorts. The current limiting devices are variable buffer resistors with a positive temperature coefficient. The current limiting tracking means are heat sinks that thermally couples the buffer resistors together such that the buffer resistors increase in resistance with a temperature increase caused by current flowing through the buffer resistor associated with the shorted battery cell. Current regulating elements are in series with columns of battery cells for preventing inrush current to the columns of the battery cells.

摘要： In a system and method for a non-contact measurement of the fly height of a slider above a magnetic data storage medium using electrostatic force, a slider with a read/write head flies over a magnetic data storage medium. A series of distinct voltages are applied between the slider and the magnetic data storage medium, and corresponding read-back signals are recorded. Using the recorded read-back signals, coefficients for an empirical curve-fit equation are calculated. The coefficients are normalized and converted into a fly height measurement.

摘要： A method for preventing electrostatic discharge (ESD) damage in the head-suspension assembly (HSA) construction process. The method includes the use of a novel GMR magnetic recording head on a conductive slider substrate, the GMR head being electrically connected to the substrate and its conducting leads having balanced resistances between the leads and the substrate. By establishing an electrical connection between the GMR head and the slider substrate, the entire HSA can be grounded during its construction. By also grounding any nearby conducting elements that could inadvertently contact the HSA or its parts, no accumulated tribocharges can discharge through the sensitive GMR sensor element.

摘要： An externally wireless laminated suspension for a hard disk drive are disclosed. In one embodiment, the externally wireless laminated suspension has an insulating layer to electrically isolate a first and second electrical trace from a conductive support layer. The second electrical trace crosses over the first electrical trace. The first electrical trace may be made of a first part on one side of the second electrical trace and a second part on the opposite side of the electrical trace. A conductive island area may be patterned into the support layer. The conductive island area may electrically couple the first part of the first electrical trace to the second part. The number of crossover points that the first electrical trace has may equal the number of crossover points that the second electrical trace has.

摘要： A method is provided for preserving the transverse biasing of a GMR (or MR) read head during back-end processing. In a first preferred embodiment, the method comprises magnetizing the longitudinal biasing layers of the read head in a transverse direction, so that the resulting field at the position of the transverse biasing layer places it in a minimum of potential energy which stabilizes its direction. The field of the longitudinal biasing layer is then reset to the longitudinal direction in a manner which maintains the transverse biasing direction. In a second embodiment, a novel fixture for mounting the read head during processing includes a magnetic portion which stabilizes the transverse bias of the read head. The two methods may be used singly or in combination.

摘要： According to an embodiment of the present invention, a slider design is presented that provides improved protection for the head/sensor of the slider. In one embodiment, the design of the slider is such that ESD protection is provided during the slider wafer process, the “back-end” processes (e.g., when the completed slider/head is incorporated into an HGA), and during operation in a disk drive or the like. In this embodiment, a conductive film is provided that surrounds the insulating-material slider substrate. The conductive film provides a grounding path during the wafer fabrication processes. This conductive layer may be further patterned during head fabrication to provide a ground path for back-end fabrication processes. A conductive stripe may be added for discharging debris in the slider-to-disk interface.
