A Luer access device may include a housing, a septum, and a gas permeable vent in communication with at least a portion of the housing for venting gas from an extravascular system. A method of venting a medical device may include providing a gas permeable vent within a Luer access device as part of an extravascular system and venting gas from the extravascular system through the gas permeable vent of the Luer access device.

An optical head has a head gimbal assembly on which a light emitting laser is mounted. A tab extends from the assembly and a photo-detector is mounted on the tab. The tab extends from the load beam of the head gimbal assembly. Alternatively, the tab extends from a flexure of the head disk assembly.

Disclosed is a disk drive having a linear actuator for carrying read/write heads into engagement with a recording medium. The heads are mounted on a carriage assembly along with a voice coil motor for driving the carriage assembly into and out of engagement of the heads with the medium. The carriage assembly slides linearly on a central guide track. A flexure is provided for the central guide track for linear movement by the carriage assembly so that initial linear movement of the carriage assembly is by flexing the flexure and further, larger linear movement of the carriage assembly is by sliding along the guide track. In one form of the invention the central guide track is suspended at the front end by a flexure and at the rear end by a bearing. In another form of the invention the central guide track is suspended at each end by a flexure. The flexure has an attaching mechanism for attaching the flexure to the central guide track so that the flexure pivots freely on the central guide track. This eliminates the likelihood of bending of the central guide track and improves the ability of the system to reject 1f and 2f run out and therefore, track following.

A linear actuator carries read/write heads into engagement with a removable cartridge having a recording disk. The magnetic heads are mounted on a carriage which moves linearly on a central guide track. The carriage moves linearly on front and rear bearings which move on a central guide track as the magnetic motor is energized. The rear bearing is elongated in the direction perpendicular to the plane of the disk to allow movement of the carriage transverse to the direction of travel. This compensates for planar misalignment of the plane of the recording disk with respect to the axis of the central track.

Elongated rear bearing for linear actuator

A cover for a disk drive is provided. The cover comprises a body portion having a relative upper surface and relative inner surface. The upper surface defines a plurality of depressions and a window opening. The inner surface is adapted to be welded to a disk drive.

In one form of the invention the central guide track is suspended at the front end by a flexure and at the rear end by a bearing. In another form of the invention the central guide track is suspended at each end by a flexure.

Inserting operational data onto a magnetic disk allows information to be transferred from a servowriter station to a verifier station. This operational data allows disk specific operational data to follow the disk without separate means for attaching data to each disk. The servowriters, which cannot write information to disks at the data sector frequency, inserts the operational data into selected greycodes in the servo sectors. When the disks are verified, the operational data may be moved from the servo sectors to the data sector in the Z-tracks for more permanent storage.

The current invention substantially removes particulate waste materials or debris from the floptical medium after laser etching. A low-temperature gas containing ice crystals is applied at a predetermined angle while the floptical medium is being rotated to improve the cleaning effect. The temperature of the disk is maintained above freezing to maintain the cleaning effect.

Method of and apparatus for removing debris from the floptical medium

The current invention provides an apparatus and method of collecting waste materials produced during laser etching of a floptical medium without blocking access to the medium surface. The invention also improves collection efficiency by applying a uniform low-pressure air around the outer edge of the medium. Because the air pressure is applied around the edge, there is no necessity to coordinate a movement or timing of the current invention with respect to the laser etching unit.

An apparatus and method for etching a point on the surface of a magnetic medium to reduce the reflectivity of the point and for verifying that proper etching occurred. A light source provides a collimated incident beam of light. The incident beam is focused to a point on the medium and a portion of the beam is reflected. The reflected beam is separated from the incident beam and the intensity of the reflected beam is measured. The measured intensity is compared to a threshold value and verification is indicated if the measured intensity exceeds the threshold value.

Apparatus for and method of verifying etching of optical servo

An apparatus for etching optical servo tracks on a magnetic storage disk comprises optics for generating a beam of light for etching the servo tracks and a spindle for rotating the disk in proximity to the optics. The device further comprises a center pin at the center of rotation of the spindle and an alignment pin which is off-center of the spindle. A disk to be etched is placed on the spindle with the center pin through a center hole in the disk hub. A pressurized gas nozzle directs bursts of pressurized gas toward the edge of the disk to rotate the disk until an alignment hole in the disk hub engages the alignment pin.
