摘要： A system (20) and method for identification of medium (41) inserted into an information storage drive optically determines whether the medium is cleaning medium by determining the translucency of the medium. The system includes a dual infra-red LED light source (28) having a controllable intensity as well as BOT and EOT light receivers (30, 32). The medium longitudinally extends between the light source and the light receivers. A medium identification controller (48) determines the type of medium inserted into the information storage drive by progressively ramping the intensity of the light source and determining at what effective driving signal value the light receivers actually receive light through the medium, and by comparing the effective driving signal value for each receiver with a calibrated driving signal value at which the light receiver actually receives light when no medium is inserted.

摘要： A wavelength router that selectively directs spectral bands between an input port and a set of output ports. The router includes a free-space optical train disposed between the input ports and said output ports, and a routing mechanism. The free-space optical train can include air-spaced elements or can be of generally monolithic construction. The optical train includes a dispersive element such as a diffraction grating, and is configured so that the light from the input port encounters the dispersive element twice before reaching any of the output ports. The routing mechanism includes one or more routing elements and cooperates with the other elements in the optical train to provide optical paths that couple desired subsets of the spectral bands to desired output ports. The routing elements are disposed to intercept the different spectral bands after they have been spatially separated by their first encounter with the dispersive element.

摘要： A tape drive emulator (30) is between a host computer (40) and a removable disk drive (22) and appears to the host computer 40 as a sequential storage system, e.g., a tape drive. However, the tape drive emulator (30) processes the data obtained from or applied to host computer 40 so that the data can be communicated to removable disk drive 22 in a manner compatible with a conventional removable disk drive. Yet in so doing, tape drive emulator 30 imposes on the data (1) an data organization, imperceptible to disk drive 22, for rendering the data expressable and locatable in a tape drive format, and (2) an additional degree of error correction that provides enhanced data integrity necessary for data backup/restore operations.

摘要： A method of monitoring input light having a plurality of spectral bands (wavelength channels) includes the following, carried out for at least two different spectral bands at different times, using a common photodetector and wavelength-monitoring circuit that is coupled to the photodetector: separating one of the spectral bands from the plurality of spectral bands, directing light in only that spectral band to the photodetector, and generating, with the wavelength-monitoring circuit, a signal representing a quality characteristic of a modulated or unmodulated pattern of light in that spectral band. Each of the plurality of spectral bands can be individually and sequentially monitored in round-robin fashion, each of a subset of the spectral bands can be individually and sequentially monitored in round-robin fashion (to provide selective wavelength monitoring), or the monitoring can be ad hoc in response to external requirements. If desired, the opitcal power of the plurality of spectral bands can be monitored by directing the light in the spectral bands other than the band that has been separated from the plurality to an additional common photodetector and a common power-monitoring circuit.

摘要： A capstanless helical scan recording system (14) comprises a supply reel (24); a take-up reel (26); and a media transport path (20) extending from the supply reel to the take-up reel. A drum (30) is positioned along the media transport path and has a read head (R1,R2) and a write head (W1,W2) mounted thereon for recording and reading information in helical stripes on the media. The take-up reel comprises a rotor assembly (60), a rotating hub assembly (70), and a gearing system. The rotor assembly includes a sun gear (80) which rotates at a first rotational speed. The rotating hub assembly rotates carries three planetary gears (160) and imparts a velocity to media transported in the media transport path. The gearing system meshes with the rotor assembly and with the hub assembly for causing the hub assembly to have a greater rotational speed than the rotor assembly. The gearing system preferably has a gear ratio on the order of about 8:1. A tension arm (44) protrudes into the media transport path and decouples the supply reel to compensate for reel runnout during high speed operation. The system has no further means other than the take-up reel and the supply reel for imparting impetus to the media along the media transport path.

摘要： In a servo tracking method and apparatus, a servo head (S) of a helical scan recorder (30) endeavors to travel equidistant between two servo signal-bearing stripes recorded on the tape (32). The recorder (30) determines a reference-crossing time at which the servo head (S) begins to cross a horizontal reference line (606) drawn with respect to the beginning of a stripe on the tape (32). The servo head (S) samples the amplitude of a servo signal provided on the tape (32) at a plurality of predetermined times after the reference-crossing time. A servo tracking circuit (175) uses the amplitude of the servo signal at the predetermined sampling times to determine how to adjust the position of said head (S) relative to the pitch of said stripe.

摘要： A system and method of adaptively modifying the control signal of a servo system during a mode of acceleration or deceleration. An error accumulator, mean generator, and feedforward generator are used to generate a feedforward signal which modifies the control signal delivered to the servo motor. The feedforward signal for a given mode of operation is determined by the mean error during the previous operation in the mode and by the feedforward signal used during the previous operation in the same mode. Each subsequent operation in the same mode improves the feedforward signal until the mean error is minimized.
