  • Implementing calibration of cooling sensitivity of embedded contact sensor (ECS) signal using thermal fly-height control (TFC) actuations
    Patent number: 8982504
    Abstract: A method, apparatus, and system for implementing calibration of cooling sensitivity of embedded contact sensor (ECS) using thermal fly-height control (TFC) actuations, by subtracting the linear part (TFC heat) from the total measured ECS signal, a profile is provided that is sensitive only to the clearance of the head-disk interface due to cooling effect for hard disk drives.

  • Media topography driven flying height modulation sensing using embedded contact sensor
    Patent number: 8824091
    Abstract: Approaches for a flying height control scheme in a hard-disk drive (HDD) device. The flying height control scheme utilizes an embedded contact sensor (ECS) to characterize the topography of a magnetic-recording disk at various flying heights of a head slider over a corresponding disk. A relation between a particular flying height and a corresponding ECS value which characterizes the media topography at that particular flying height is represented in disk topography data. The disk topography data is accessed and used for active flying height control for the head-disk interface in view of the current ECS value.

  • THERMOELECTRIC VOLTAGE-BASED DIFFERENTIAL CONTACT SENSOR
    Publication number: 20140153130
    Abstract: Approaches for a hard-disk drive (HDD) comprising a head slider comprising a thermoelectric embedded contact sensor. The thermoelectric embedded contact sensor may comprise a first and second conductive lead and a metallic component. The metallic component has a different Seebeck coefficient than the first and second conductive leads. A thermoelectric voltage across the metallic component is used to measure the distance between a head slider and a magnetic-recording disk without supplying an electrical current from a hard-disk drive to either of the first conductive lead or the second conductive lead.
