A storage device having an automatic backup function, which is connected to a host apparatus to store user data, is provided. The storage device includes a storage medium which stores the user data, and a controller which controls data writing and reading of the storage medium. The controller backs up at least a portion of the user data stored in the storage medium in an available region of the storage medium when the storage device is in an idle mode.

Disclosed herein is a system for diagnosing a deficient pulse and an forceful pulse. The system includes a pulse diagnotic device, a deficient pulse and forceful pulse determining device, and an output device. The pulse diagnotic device measures pulse condition information at an examinee's Cun (˜\f˜) Gu (H), and Chi (,R) pulse-taking locations on his or her wrist using one or more pulse-taking sensors. The deficient pulse and forceful pulse determining device is operably connected to the pulse diagnotic device, analyzes the pulse pressure information measured by the pulse diagnotic device, calculates a quantified deficiency/forceful coefficient, and determines whether a pulse of interest is a deficient pulse or an forceful pulse. The output device is connected to the determining device and displays results of the determination.

A method for forming a storage node contact plug in a semiconductor device is provided. The method includes: forming an inter-layer insulation layer over a substrate having a conductive plug; etching a portion of the inter-layer insulation layer using at least line type storage node contact masks as an etch mask to form a first contact hole with sloping sidewalls; etching another portion of the inter-layer insulation layer underneath the first contact hole to form a second contact hole exposing the conductive plug, the second contact hole having substantially vertical sidewalls; and filling the first and second storage node contact holes to form a storage node contact plug.

A method for fabricating an isolation layer in a semiconductor device includes providing a substrate, forming a trench over the substrate, forming a liner nitride layer and a liner oxide layer along a surface of the trench, forming an insulation layer having an etch selectivity ratio different from that of the liner oxide layer over the liner oxide layer, forming a spin on dielectric (SOD) oxide layer to fill a portion of the trench over the insulation layer, and forming a high density plasma (HDP) oxide layer for filling the remaining a portion of the trench.

The invention includes a testing method which may be applied to at least one writer in a disk drive during the self-test phase to generate write parameters, focused on the Over Shoot Control (OSC) of the write current parameter to improve the reliability of write operations by that writer. The Minimum OSC is used for write operations in normal temperatures. The Optimum OSC is used for a first lower temperature range, preferably between essentially 15 degrees Centigrade and essentially 5 degrees Centigrade. The Maximum OSC is preferred below essentially 5 degrees Centigrade. The Minimum OSC should preferably guarantee both an Adjacent Track Write (ATW) criteria, as well as guarantee a Write Induced Instability (WII) criteria. The invention includes the write parameter collection, as well as the disk drive containing the generated write parameter collection. The invention also includes the method of using that write parameter collection to control a writer while writing to tracks belonging to the radial zone collection and program systems implementing the invention's methods.

There is provided a magneto-resistive head in a hard disk drive. In the magneto-resistive head, an upper write pole has a write track width, and a lower write pole is positioned under the upper write pole, separated by a predetermined write gap. A magneto-resistive sensor is positioned under the lower write pole, apart by a predetermined gap and orthogonally to the length of the write gap, and has a predetermined read track width, for efficiently reading data from a disk. A shield is positioned under the magneto-resistive sensor, separated by a predetermined gap.

A servo burst recording and servo control method for a magnetic storage device having a magneto resistive (MR) head comprises the steps of recording an additional burst signal having a magnitude as large as the quantity of track shift caused by a displacement angle of the MR head around each center line of each track, and using the additional burst signal as position identification information for the MR head during servo control thereof. The additional burst signal can be used during a read operation only or during a write operation only.

A method for fabricating a semiconductor device includes forming a fuse over a substrate, the fuse having a barrier layer, a metal layer, and an anti-reflective layer stacked, selectively removing the anti-reflective layer, forming an insulation layer over a whole surface of the resultant structure including the fuse, and performing repair-etching such that part of the insulation layer remains above the fuse.
