摘要： An optical disk has groups of features (such as depressed areas) arranged in a preselected position sensing servo pattern, and a flat, non-grooved surface between a plurality of circumferentially spaced sectors. A single photodetector senses the change in amplitude of reflected light as a spot from a laser passes over one of the features and generates position sensing signals corresponding to the pattern. At least three phases of the position sensing signal are generated for each sector. Each phase is determined by edges on the disk offset circumferentially with respect to each other and separated radially from each other by a preselected critical distance that is independent of the pitch of the recording tracks on the disk to provide a track error signal that is substantially linear within a desired range to either side of a zero-crossing point.Each even sector includes a plurality of features formed in an arrangement which is the complement and/or reversal in order circumferentially of their arrangement in the intervening odd sectors to cancel simultaneously, by averaging the position sensing signals from adjacent sectors, errors caused by variations in pattern size and/or radial velocity of an optical head as it moves generally radially of the disk.

摘要： The invention provides a novel wavelength-separating-routing (WSR) apparatus that uses a diffraction grating to separate a multi-wavelength optical signal by wavelength into multiple spectral channels, which are then focused onto an array of corresponding channel micromirrors. The channel micromirrors are individually controllable and continuously pivotable to reflect the spectral channels into multiple output ports. As such, the inventive WSR apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. The WSR apparatus of the present invention may be further equipped with servo-control and spectral power-management capabilities, thereby maintaining the coupling efficiencies of the spectral channels into the output ports at desired values. The WSR apparatus of the present invention can be used to construct a novel class of dynamically reconfigurable optical add-drop multiplexers (OADMs) for WDM optical networking applications.

摘要： A system and method for replicating magnetic patterns on hard disk media includes a mask located over or above a magnetic recording layer. The recording layer may include a single, dual, or multi-layer recording layer. A pattern is or has been formed in the mask, where the pattern defines the recordable regions and the non-recordable regions to be created in one or more layers within the recording layer. Portions of the recording layer are then exposed. An etch may then be performed to create grooves within one or more layers in the exposed regions of the recording layer. The magnetic properties of at least one layer in the exposed portions of the recording layer are then altered in order to create recordable or non-recordable regions. The mask is then removed from the recording layer.

摘要： Radial correction factors are calculated for each ruler on a patterned media in a data storage system. A ruler is a position-sensing pattern that defines the radial position of a recording head. Rulers are patterned onto each disk before the disks are assembled into a storage system. The radial correction factors are then added to the measured position information during read and/or write operations of the data storage system. The radial correction factors correct for any radial misalignment created by disturbances in the data storage system. Circumferential correction factors are calculated for each patterned media in the data storage system. A corrected sector number is then determined by redefining the original sector numbers using the circumferential correction factors.

摘要： A servo sector format for a patterned media, such as a magnetic media, includes a first patterned servo timing mark, a patterned gray code, a plurality of PES burst separators, and a second patterned servo timing mark. The first patterned servo timing mark indicates the start of a servo sector. The plurality of PES burst separators are areas where no data can be written. A plurality of servo burst fields are written magnetically between the plurality of PES burst separators, and are used to determine at least one position error signal. The servo sector format further includes magnetically written gray code positioned after the second servo timing mark. The patterned gray code is used in addressing the tracks located on the surface of a disk when the magnetically written gray code is self-written.

摘要： The present invention proposes a new servo track writing technique called Extended Copying with Head Offset (“ECHO”). The read and write elements of the read/write head are offset from each other. A servo writer writes a guide pattern on the magnetic media disc. ZAP correction factors are added to the guide pattern. The head disc assembly is then connected to an electrical control system for self-propagating servo writing. The actuator arm is displaced until the read head is aligned over the guide pattern. A new servo track is written by the write element. ZAP correction factors are added to the newly written servo track. The actuator arm is displaced until the read element is aligned with the newly written servo track. A new servo track is written. ZAP correction factors are added to the newly written servo track. The process is repeated until a desired number of servo tracks are written.

摘要： A system and method is disclosed for correcting gain and offset errors in a signal amplifier for a position sensitive detector. The present invention eliminates the need to perform division for normalization by holding constant a signal proportional to the sum of the two signals generated by the position sensitive detector. First the two signals generated by the position sensitive detector are pulse-width modulated with a common variable duty cycle clock, and then the resulting modulated signals are low-pass filtered to extract the DC component. The duty cycle is varied so that the sum of the two DC components is held constant. In the preferred embodiment, the means for varying the duty cycle are closed-loop feedback and open-loop feed forward. The closed-loop feedback gives long term accuracy and the open-loop feed forward gives rapid settling time. Once the sum of the DC components of the modulated signals is held constant, the individual DC components of the modulated signals are normalized and may be used for servo or other applications.

摘要： A method of pre-processing sampled data prior to estimating the peak amplitude of a pulse includes averaging of two adjacent sample values. Pre-processing makes the peak amplitude estimation less sensitive to the sampling phase relative to the peak position and consequently allows for the use of a lower sampling period relative to the full-width-half-maximum pulse width for a given peak estimation accuracy. The method incorporates a step in which a base line offset signal is subtracted from an estimated peak value, and multiplying the consequent pulse peak amplitude estimate by a predetermined constant in order to compensate for a systematic change in a final peak amplitude estimate. The multiplying constant may have a value derived from estimated peak values of other detected pulses in order to compensate for a systematic change in the peak amplitude estimate. Offsets in a position error signal derived from such pulses are eliminated by subtracting the estimated peak amplitudes of a pair of proximate (spatially and temporally related) pulses. The difference of another pair of proximate pulses is used to estimate the maximum peak amplitude of each pulse. A position error signal difference is divided by a maximum peak amplitude difference to generate a normalized position error signal that compensates for systematic changes of pulse signal amplitude estimate caused by adjacent sample averaging.
