摘要:
A magnetic media for heat assisted magnetic data recording. The magnetic media includes a thermal insulation layer structure formed near the substrate of the media provide more efficient heating of the write layer by allowing less heat dissipation to the substrate. The thermal insulation layer structure can be one or more layers of an oxide such as SiO2 and one or more layers of a material such as NiTa. Increasing the number of oxide layers and NiTa layers increases the thermal insulation of the thermal insulation layer structure thereby further increasing the efficiency of the heat assisted writing.

A thermally-assisted recording (TAR) disk drive uses “shingled” recording and a rectangular waveguide as a “wide-area” heat source. The waveguide generates a generally elliptically-shaped optical spot that heats an area of the recording layer extending across multiple data tracks. The waveguide core has an aspect ratio (cross-track width to along-the track thickness) that achieves the desired size of the heated area while locating the peak optical intensity close to the trailing edge of the write pole tip where writing occurs. The large cross-track width of the waveguide core increases the volume of recording layer heated by the optical spot, which reduces the rate of cooling. This moves the peak temperature point of the heated area closer to the write pole tip and reduces the temperature drop between the peak temperature and the temperature at the trailing edge of the write pole tip where writing occurs.

An integrated microactuator slider. The microactuator includes a substrate having a fixed portion and a moveable portion. The microactuator also includes a slider communicatively integrated within the moveable portion of the substrate. The slider includes a read/write head for reading data from or writing data to a data storage device. The microactuator further includes a force generator communicatively integrated within the substrate. The force generator is for causing movement of the moveable portion of the substrate.

Approaches for a hard-disk drive (HDD) baseplate comprising a recessed region that provides additional clearance for a disk. The protective enclosure of the HDD comprises a baseplate. The surface of the baseplate, which opposes a magnetic-recording disk, comprises a recessed region near the outer diameter (OD) of the magnetic-recording disk. The recessed region prevents the disk from being damaged through inadvertent physical contact with the baseplate, which may arise when the HDD receives a mechanical shock. The recessed region may be designed to minimize the damage to the disk if physical contact between the disk and the baseplate does occur. The recessed region may have a variety of shapes, such as a circular indentation or one or more non-contiguous regions in the baseplate where physical contact between the disk and the baseplate is deemed likely to occur.

A device for providing an external display and keypad for a smart-phone. The device has a port for receiving the smart phone. The device does not have its own computing power, but uses the computing power of the smart phone itself, thereby allowing the device to be smaller, lighter and less expensive than a standard lap-top computer not notebook device. The device is configured with a port for receiving a smart-phone and preferably holds the smart phone so that does not extend above the surface of the device or is flush with the surface of the device. The device can also be configured to allow the smart phone itself to act as a numerical keypad adjacent to the keypad provided on the device.

A magnetic head is described herein. A method for manufacturing the magnetic head comprises determining a protective distance for a protective structure to extend beyond an element in a direction toward a disk, layering the protective structure, and removing material from the protective structure to obtain approximately the protective distance. The protective distance is from an element end to a protective structure end. The protective distance is determined based on a magnetic head profile. The thickness of the protective structure is based on pole-tip recession.
