Abstract: A block storing corrupt data is detected. Based on detecting the block storing corrupt data, threshold voltage (VT) distribution data corresponding to the block is accessed. The VT distribution data comprises one or more VT distribution measurements corresponding to the block. The VT distribution data corresponding to the block is compared with reference VT distribution data. The reference VT distribution data comprises one or more reference VT distributions. Based on a result of the comparison, it is determined whether to perform one or more heroic data recovery processes on the block.

Abstract: Aspects of the present disclosure configure a system component, such as memory sub-system controller, to dynamically decode read data for zone-based memory allocations. The memory sub-system controller reads an entire memory block or zone. The memory sub-system controller decodes a first portion of the memory block or zone using a first decoding process. The memory sub-system controller determines that a second portion of the memory block or zone satisfies a criterion. In response, the memory sub-system controller applies a second decoding process to decode the second portion.

In one embodiment, a disk surface is provided with a write head associated therewith. The disk surface has a data track having a width. An embedded runout correction (ERC) field is written onto the disk surface, wherein the ERC field has a width that is greater than the width of the data track.

Abstract: Detecting flaws in a disk drive includes sampling a read signal provided by reading a data pattern from a disk to obtain samples, obtaining significant samples from the samples, deriving a value from the significant samples, and reporting a flaw if a comparison between the derived value and a threshold value is unacceptable.

Abstract: A method and apparatus for detecting flaws requiring sparing of portions of storage media included as part of a hard disk drive are provided. A window of a selected portion of the storage medium is formed, and the density of defects detected within that window is calculated. If the density of defects exceeds a threshold amount, a signal is passed to the controller. The portion of the storage media containing the defects that caused the generation of the flag may then be spared. The present invention allows the potential for detected defects to significantly affect the ability of the storage medium to be assessed. Furthermore, the present invention does not require that the location of each defect be stored in memory. Accordingly, the present invention is economical to implement, and allows defects to be assessed in substantially real time and with improved accuracy.

Abstract: A hybrid capillary/mechanical two-phase thermal loop has a sensor connected in parallel with a number of evaporators to regulate the flowrate of a booster pump providing working fluid to the evaporator capillaries. This sensor is made of a coiled, conductive tube connected in parallel with the evaporators, with an inside diameter substantially greater than the inside diameters of the evaporator capillaries. A conductive wire extends within said tube, but is insulated from electrical contact with the tube. The working fluid contained within the tube acts as a dielectric between the tube and wire. The amount of liquid phase working fluid within the tube can be determined by measuring the electrical capacitance between the tube and wire. The flowrate of the booster pump is then regulated as a function of the measured capacitance to maintain a substantially constant amount of liquid phase working fluid within the sensor tube.
