摘要： A method of thermally bonding lubricant over a surface of a magnetic disk in a disk drive involves providing a heat source at an air bearing surface (ABS) of a magnetic head; causing the heat source to be energized to produce heat; and causing the magnetic head to be moved across a surface portion of a magnetic disk so that lubricant is thermally bonded over the surface portion from the heat produced by the heat source. Preferably, this lubricant bonding mode of operation is performed on a regular or periodic basis. Alternatively, the mode is activated based on a predetermined environmental condition (e.g. temperature or humidity) or from an external signal. In one example, the heat source is comprised of first and/or second pole pieces of the magnetic head through which an electrical current is passed. In another example, the heat source is comprised of a separate heating element which is formed on or within the magnetic head (which may be the same heating element utilized for thermal-assist writing to the magnetic disk). In yet another example, heat for thermally bonding lubricant is generated by reading data from a data block on the magnetic disk and writing the data back to the data block in a repetitive fashion.

摘要： An electronic apparatus includes a base, a main body and a lock mechanism. A main body is rotatably supported on the base and having a display unit. A lock mechanism prevents the main body from rotating with respect to the base. The main body includes the display unit and a magnetic disk drive. The magnetic disk drive includes a magnetic head and a safety unit. The magnetic head accesses a recording medium. A safety unit moves the magnetic head to a save position where the magnetic head is safe in the magnetic disk drive when the lock mechanism is unlocked. The safety unit move the magnetic head to start a seeking operation over the recording medium when the lock mechanism is locked.

摘要： A fly height detector apparatus and associated method for detecting the fly height of a read/write head spatially disposed from a data storage surface during a data transfer operation. The fly height detector apparatus comprises a receiver circuit measuring the frequency of the read/write head; a perturbation deliverable to the gap between the read/write head and the data storage surface to invoke a dynamic response in the read/write head; and a processor circuit responsive to the receiver circuit to derive a fly height in relation to the dynamic response frequency. The processor circuit comprises a memory in which is stored a numerical model describing a functional interrelationship between the fly height and the read/write head frequency.

摘要： Provided is a magnetic disc apparatus comprising a magnetic head for writing and reading data to and from a magnetic disc, a slider for floating up the magnetic head from the magnetic disc on rotation, a suspension having an IC chip mounting surface, for supporting the slider, a positioning mechanism for positioning a magnetic head at a predetermined position, and an IC chip mounted on the IC chip supporting surface of the suspension, wherein the rate of variation in temperature difference between opposite sides of the IC chip mounting position as a center on the IC chip mounting surface is set to be below about 3.5 K/sec. Thereby it is possible to restrain the averaged seek time for the magnetic disc from becoming longer.

摘要： A micro-actuator of a head suspension either is wired in a reverse polarity to effect movement of the suspension arms in opposing directions relative to the magnetic disks or reversed in physical orientation and wired identically. This permits a single micro-actuator control signal to control all micro-actuators and thereby cancel the affects of inertia of the suspension arms and the read/write heads on the actuator arms as half of the suspension arms and magnetic heads move in one direction while, simultaneously, the other half of the suspension arms and magnetic heads move in a second, opposite direction in response to a single control signal, simplifying wiring and control electronics. The counter-movement of the suspension arms and magnetic counter the inertia and inertial forces and expedite the settling into their stable recording/reading positions, thereby reducing seek times and improving disk drive performance.

摘要： In a disk storage apparatus, a CPU (2) supplies control current of a rated maximum current value to a VCM (6) at the time a head is loaded onto a disk. When the head is stopped on the head stop member, the CPU (2) controls an additional drive circuit (12) to conduct re-try processing. The additional drive circuit (12) supplies to the VCM (6) a control current whose current value is added to the rated maximum current value.

摘要： A disc drive includes a disc, a beam extending from the voice coil motor to a gimbal point to provide a load force, and a slider that flies over the disc with a pole tip protrusion that has an ambient temperature sensitivity. The disc drive also includes a strut with a yielding bend section (YBS). Deposits of shape memory alloys (SMA) having different first and second transformation temperature ranges are deposited on the yielding bend section (YBS) and effectively reduce an ambient temperature sensitivity of the pole tip protrusion.

摘要： In order to avoid destruction of recorded data on the magnetic disk due to a shock when portable equipment incorporating a magnetic disk falls from a person's hand or similar, or to minimize damage to the magnetic head and magnetic disk device, in the portable equipment incorporating a magnetic disk device, the magnetic disk device 1 is provided with a magnetic head retraction mechanism and with a held-in-hand detection mechanism which detects whether the equipment is held in a person's hand. When the held-in-hand detection mechanism detects that the equipment is not held in a person's hand, the retraction mechanism causes the magnetic head 5 to be retracted from the recorded data portion of the magnetic disk 3 to the outside, so as to protect the magnetic disk device 1 and the data recorded on the magnetic disk from shocks.
