Abstract: A method, apparatus, and computer-readable medium for supporting multiple users working on a project includes a project server. Projects are divided into a plurality of revision units based on the type of each of the plurality of objects and the relationships between the plurality of objects. The division of the project into a plurality of revision units can be facilitated by determining that an object type of an object is included in a user defined list of objects to be designated root objects of a revision unit. Objects having an object type not included in the user defined list of objects to be designated as root objects are designated non-root objects and associated with a revision unit of a root object that the non-root object branches from. Projects divided into a plurality of revision units can be stored in a database in communication with the project server.

Abstract: Enhancement of the supercontinuum generation performance of a highly-nonlinear optical fiber (HNLF) is accomplished by incorporating at least one Bragg grating structure in the HNLF. The Bragg grating results in reflecting a core-guided signal into signal which also remains core-guided. The supercontinuum radiation generated by such an arrangement will exhibit a substantial peak in its energy at the grating resonance of the Bragg grating and a region of increased radiation in a narrow wavelength band on the long wavelength side of the peak. A number of such Bragg gratings may be formed so as to “tailor” the enhancements provided in the supercontinuum radiation. Various, well-known Bragg grating modifications (tuning, chirped, blazed, etc.) may also be used in the inventive structure to enhance the generated supercontinuum.

Abstract: A method for measuring a surface recession of a magnetic recording head using a flying height tester. The recording head has a trailing edge portion that extends from an air bearing surface. The trailing edge portion contains the read/write elements of the recording head. Manufacturing processes typically create a recession in the trailing edge portion. The recession is measured by placing the slider adjacent to a rotating transparent substrate of a flying height tester. A light beam is then directed through the substrate and reflected off of the slider. The reflected light beam is detected to compute a flying height between the substrate and the point of reflection on the slider. The light beam is reflected off various points on the air bearing surface and the trailing edge portion to measure a number of different flying heights. The various flying heights are then used to compute the recession in the slider.

Abstract: A method and apparatus for measuring the flying height of a recording head that is separated from a rotating disk by an air bearing. The recording head has a trailing edge that extends from an interface of a substrate. The trailing edge has an embedded read/write element and an outer tip. The recording head is loaded into a flying height tester that can measure the distance between the disk and any point on the head. The flying height tester contains a transparent disk that is rotated to create an air bearing between the head and the disk. The outer tip is separated from the disk by an air bearing height h.sub.m. The read/write element is separated from the disk by an air bearing height h.sub.g. The substrate interface is separated from the disk by an air bearing height h.sub.i. The flying height tester measures the height h.sub.g to obtain the distance between the read/write element and the disk.

Abstract: A slider which has a totally reflective surface that can be used by an optical measuring system to measure the air bearing height of a head gimbal assembly ("HGA"). The slider has a rail with a recess area. The rail is coated with a first film that is thin enough to allow a light beam to transmit through the film and reflect from an interface within the slider. The recess contains a second film that does not transmit light so that a directed light beam is totally reflected from the second film. The outer air bearing surface of the first film is separated from the outer surface of the second film by a height H which is measured before the HGA is tested. The HGA is then placed adjacent to a rotating disk to create an air bearing with a height Hp. The outer surface of the second film is separated from the disk by a height Hv. An optical system directs a light beam into the recess to measure the height Hv between the disk and the outer surface of the second film.

Abstract: A monitor and method for monitoring the optical properties of a recording head of a hard disk drive. The monitor includes a light source that reflects a light beam off of the recording head. The reflected light beam is detected by a photodetector. The light beam directed onto the head has an intensity Ii. The light beam reflected from the head has an intensity Io. The photodetector and light source are coupled to a controller which calculates a reflectance R based on the ratio of the intensities Ii and Io. The reflectance R is a function of the optical properties of the recording head. The calculated reflectance R is compared with a threshold value. If the reflectance R exceeds the threshold value the monitor may provide a part fail message which indicates that the optical properties off a particular head deviates from a range of values. The present invention provides a means to quickly monitor the optical properties of recording heads without actually measuring the properties.

Abstract: The present invention provides a calibration standard for the uniform calibration of flying height testers. The calibration standard comprises a head assembly held in contact with a transparent disc through the use of a load spring. The transparent disc has a plurality of grooves formed in a surface facing the head assembly. A cover case is attached to the glass disc at one end and provides a sealed environment for the interface between the head assembly and the transparent disc.

Abstract: A calibration standard for uniformly calibrating flying height testers. The calibration standard includes a wedge slider held in contact with a glass disc by a load bridge, load spring and cover case. The wedge slider has a first rail and a second rail extending along its length and has a raised end to form an optical wedge between the glass disc and the first and second rails. A profilometer is used to map any surface irregularities on the surfaces of the first and second rails facing the disc, allowing the calculation of an accurate expected distance, or flying height, between the surfaces and the disc at each horizontal location along the length of the wedge slider. The expected flying height is compared to a flying height measured through optical interference techniques to calibrate the flying height tester.
