    摘要: Pre-aligned, kinematically mounted modules including processing lasers, beam trains, and individually calibrated control beams are quickly and easily replaced on subassembly bases with minimal in situ alignment, and can maintain working-spot position to micron tolerances over ambient temperature variations of ±10° C. Subassembly bases, with features for kinematically mating to a plurality of pre-aligned laser modules and to a platform base incorporated in the laser processing tool, enable multi-module subassemblies to be quickly replaced with spare subassemblies of the same type, or swapped for subassemblies of a different type. The mating features and reversible locks are designed to mitigate thermal effects that are often a dominant cause of alignment drift in processing lasers.

    摘要: Adjustment of a tunable external-cavity laser is simplified by incorporating a mount that includes a base, a main body, a reflecting surface, a diffracting surface and a hinge coupling the main body to the base. The laser additionally includes a light source, a converging lens located to receive light from the light source, a tuning mirror and a pivoting arm on which the tuning mirror is mounted. The main body is bounded in part by two plane, external surfaces orthogonal to a common reference plane and angularly separated from one another by an angle. The reflecting surface has a spatial orientation defined by one of the external surfaces and is arranged to receive light from the lens. The diffracting surface has a spatial orientation defined by the other of the external surfaces, and diffracts light received from the reflecting surface towards the tuning mirror. The hinge is located opposite the angle and parallel to the reference plane.

    摘要: A device for formatting a linear data storage tape includes a servo write head configured to write a pattern of magnetic transition stripes along a servo band of the linear data storage tape. The servo write head is configured to produce stripes having lateral widths that are significantly greater than that of a servo read element of a data read/write head designed for use with the linear data storage tape. Each stripe has either a positive non-zero azimuth or a negative non-zero azimuth. The device also includes a magnetic readback element that produces a servo verify signal. The magnetic readback element extends laterally across the full widths of the magnetic transition stripes and is oriented at an azimuth between the positive and negative non-zero azimuths of the magnetic transition stripes. A pulse detector is configured to detect pulses in the servo verify signal. Defect detection logic counts the numbers of pulses in the servo verify signal and compares such numbers with expected numbers to detect defects. Defects are also detected by identifying any pulses that exceed a predefined maximum threshold.

    摘要: A high density helical scan recording device having write/wide-read heads and RAW/narrow-read heads of different widths to permit an increase in the density of data tracks and to allow backward compatibility for reading and recording conventional density data tracks. The write/wide-read heads are used to record data in tracks of either the conventional density or the high density. The write/wide-read heads are also selected to read conventional density data tracks. The RAW/narrow-read heads have a reduced width that permits reading of data tracks in which greater than two-thirds of each data track has been overlapped by an adjacent data track. The RAW/narrow-read heads are used in a read-after-write (RAW) capacity and are used during a read operation of the high-density data tracks.

    摘要: The invention provides a system and method for reliably and accurately measuring the gap between two materials when the depth of gap is less than the smallest distance that an optical thickness gauge (OTG) is able to measure. The invention is practiced by forming a suitable slot (or a groove, channel, hole or other suitable deformation) having a precisely known depth in at least one material. The sum of the distance of the gap and the depth of the slot is at least equal to the smallest distance that the OTG can measure. The slot is positioned over the materials and under the OTG probe head such that a cavity is formed. The depth of the cavity is measured. Since the distance of the slot is known, the depth of the gap is determined by subtracting the known depth of the slot from the measured depth of the cavity.

    摘要: A magnetic head suspension assembly and method are designed to include a substantially inflexible support arm mounted at one end to an actuator motor in a data storage disk drive system. At the opposite end of the support arm is a gimbal. An air bearing slider having at least one read/write head is connected to the gimbal. The gimbal is adapted to accommodate pitch and roll motion and is compliant in the direction perpendicular to a surface of the data storage medium to be read. The gimbal is parallel-coupled with a load spring that is connected to the support arm to apply a load force. This arrangement improves the shock-resistance characteristics of the suspension assembly, since the support arm does not add to the inertial force caused by accelerations from shock events. In a preferred embodiment, the electrical connection to the read/write head is via electrical traces that are printed onto the support arm and gimbal. Traces are also formed on the gimbal springs to extend to a solder-reflow location at an interface to the slider.
