Abstract: A method for interconnecting multiple components of a head-gimbal assembly with a solder joint, including the steps of positioning a first component adjacent to and at an angle relative to a second component to provide a connection area between the first and second components, dispensing a solder sphere to a capillary tube having tapered walls, wherein the capillary tube is positioned with an exit orifice above the connection area between the first and second components, pressurizing the capillary tube until a predetermined pressure is reached, applying a first laser pulse to the solder sphere to liquefy the solder sphere until it falls from the exit orifice, waiting for a predetermined time period after the liquefied solder sphere has exited the exit orifice of the capillary tube, and applying a second laser pulse to reflow the solder sphere to create the solder joint between the first and second components.

Abstract: A storage device includes a controller that determines a degree of data degradation for a data track targeted by a pending read command and sets a head/media clearance parameter for execution of the read command based on the determined degree of data degradation for the data track, the head/media clearance parameter providing for a greater head-media separation when the determined level of degradation is lower than when the determined level of degradation is higher.

Abstract: The presently disclosed technology teaches integrating disc drive electronics into a transducer head. Decreased electrical transit times and data processing times can be achieved by placing the electronics on or within the transducer head because electrical connections may be made physically shorter than in conventional systems. The electronics may include one or more of a control system circuit, a write driver, and/or a data buffer. The control system circuit generates a modified clock signal that has a fixed relation to phase and frequency of a bit-detected reference signal that corresponds to positions of patterned bits on the disc. The write driver writes outgoing data bits received from an external connection to off-head electronics directly to the writer synchronized with the modified clock signal. The data buffer stores and converts digital data bits sent from the off-head electronics to an analog signal that is synchronized with the modified clock signal.
