The technology described in this document can be embodied in a viewing apparatus for a surgical device, the apparatus including a lens assembly including a first polarizer, a display device configured to present an image of a surgical scene, and a reflective surface oriented at an acute angle with respect to the display device such that light from the display device is reflected from the reflective surface towards the lens assembly. The first polarizer in the lens assembly is configured such that light reflected from the reflective surface passes through the first polarizer, and light reaching the first polarizer without being reflected from the reflective surface is substantially blocked.

Various aspects of the present disclosure provide tamper-evident seals and methods for indicating tampering with an apparatus using the tamper-evident seals. One such tamper-evident seal includes a base layer and a pattern-release layer on a periphery area of the base layer. In such case, the pattern-release layer includes a first adhesive configured to leave a residue on the printed circuit board assembly, and the base layer has a central area that is surrounded by the periphery area and free of the first adhesive.

Tamper-evident seals having adhesive-free areas to minimize rework time

A head stack assembly (HSA) for a disk drive includes an actuator body having a cylindrical bore therethrough and an actuator arm extending therefrom. A head is attached to a distal end of the actuator arm. A pivot bearing cartridge is disposed within the cylindrical bore. A tolerance band is radially preloaded between an outer surface of the pivot bearing cartridge and an inner surface of the cylindrical bore. The cylindrical bore has a first diameter in a first region adjacent a first axial end, and a second diameter in a second region adjacent a second axial end. There is a radial step between the first and second regions. The first diameter is greater than the second diameter by at least 20 microns but no more than 100 microns.

A method of manufacturing a suspension for a disk drive includes providing and assembling an actuator coupling plate, a bend region, a load beam, and a head receiving gimbal. The load beam has a first end and a second end and defines a longitudinal axis that bisects the first end and the second end. The load beam is coupled to the gimbal proximate the first end and includes a base region proximate the second end, the base region having a first lateral section to one side of the longitudinal axis and a second lateral section to another side of the longitudinal axis. The first and the second lateral sections define a gap therebetween, and the base region has a bridge extending across the gap. A constraint layer overlays the gap and the bridge.

Method of manufacturing a disk drive suspension

A C-shaped bobbin includes a bobbin base member adjacent and attached to a first lateral leg of an actuator coil. A bobbin recess, adjacent the bobbin base member, separates first and second bobbin wings. The first and second bobbin wings define first and second wing lengths measured parallel to first and second longitudinal legs of the coil, respectively, and also define first and second wing widths measured normal to the first and second longitudinal legs, respectively. The bobbin recess defines a recess depth measured normal to the first lateral leg, and defines a recess width measured parallel to the first lateral leg. Each of the first and second wing lengths is less than the length of the longitudinal legs. The recess depth is at least half a base member width. The recess width is at least twice the first wing width and/or the second wing width.

A suspension for a disk drive includes a gimbal, a load beam and a constraint layer. The gimbal is configured to receive a head. The load beam has a first end and a second end and defines a longitudinal axis between the first end and the second end. The load beam is coupled to the gimbal proximate the first end and includes a base region proximate the second end, the base region having a first lateral section to one side of the longitudinal axis and a second lateral section to another side of the longitudinal axis. The first and the second lateral sections define a gap therebetween, and the base region has a bridge section extending across the gap between the first lateral section and the second lateral section. The constraint layer overlays at least a portion of the base region.
