摘要： A magnetic disk drive includes redundant data written at a plurality of out of phase angular locations to reduce the latency and enhance performance during a read operation. The loss of recording capacity is reduced by increasing the data density to achieve the same soft error rate standard required for single recording. Dual recording also allows different recording codes to be used at the duplicated locations to thereby have the more highly stressed code words occur at different locations in the data to further reduce the possibility of an error. The redundant recording can be used in one portion of the media and normal recording used in another media portion to enable selection of the recording technique in accordance with the type of data being stored. The size of the normal and redundant recording portions can be controlled by the format operation and the user of the disk drive can intervene to designate the size of the redundant and normal media recording portions effected during the format operation.

摘要： Amplitude information is derived from a periodic waveform by digitally sampling the periodic waveform, filtering a digital harmonic signal out of the digital sample sequence of the periodic waveform, and computing the root mean square of the digital Mth harmonic signal over a predetermined number of successive samplings of the periodic waveform. The digital sampling is done at a rate such that there will be an integer number of samples "L" over the period of the first harmonic component of the digital sample sequence of the waveform signal. The root mean square value computation is simplified by selecting the sampling window width N and the harmonic M so that there is a predetermined relationship to a critical sampling number L given by the expression, L=(4MN)/(2j+1) where j=0, 1, 2, . . . . As long as this relationship is satisfied, the RMS value can be computed by summing the absolute value of selected digital amplitude values of the selected harmonic component of the digitized signal. Further, the RMS values may be averaged by nesting a number of successive indexed RMS value computations.

摘要： A disk drive stores multimedia data in long spiral data tracks. The tracks on opposite surfaces of the disk spiral in opposite directions, so that a track on one surface can be read as the actuator sweeps in, and a track on the opposite surface can be read as the actuator sweeps out. Because the actuator only follows spiral tracks without performing long seek operations, the actuator motor can be reduced in size and stresses on actuator bearings and other parts are reduced. Additionally, due to reduced disturbances associated with seeks, it is possible to follow tracks more closely and therefore reduce the width of individual tracks. Further cost reductions are accomplished by spinning the disks at a slower speed and reducing the size of the spin motor accordingly. Finally, data density can be increased simply because multimedia data does not require the same low error rate as conventional data. Preferably, a group of disk drives optimized for multimedia data is used to form a video-on-demand system. Compressed, interleaved portions of a video presentation, such as a motion picture, are stored in blocks on the spiral tracks. The drives read the blocks on one spiral track at a time from beginning to end, placing the data from these blocks in a set of buffers corresponding to different short time intervals. Video signals are output from the buffers. Any short time interval of the presentation can be accessed on demand by switching to the appropriate buffer.

摘要： In a storage device, such as a magnetic rigid disk drive, data is stored at varying linear densities in the user data storage portions to increase the effective storage capacity of the device as a function of the differences in soft error rate tolerance associated with the various types of data being stored and the ability of non-alphanumeric data to be enhanced by reconstruction or smoothing rather than by an error correction code. A data type signal included with incoming data dictates the recording frequency and a control signal associated with the recorded data block is read when data is addressed to appropriately adjust the clock frequency for reading such addressed stored data.

摘要： An original image or other data sequence is modified with an internal marker value, and is communicated (stored and/or transmitted) as one component of a transform having multiple complementary components. The image is restored in a closed form, without iteration, and in some cases without any loss of precision from the original image. The original image may have complex element values. Multiple original images may be combined, and separated after restoration. Several types of maps may be embedded in or packaged with the communicated component. Communicated component elements may be stored with variable lengths.

摘要： An image in a base domain (e.g., spatial) is restored from only one component (e.g., magnitude) of a transform-domain (e.g., Fourier) image by combining this component with a complementary component (e.g., phase) of a transformed previous iteration. Every iteration is converted to the base domain, and predefined known marker and padding data is reapplied to the iteration during every iteration, for convergence purposes. The restored image can be scaled and trimmed, and the marker position interpolated. The original image to be restored is modified to contain the known marker and known padding at known locations. These may be inserted in the base domain or in the transform domain.

摘要： The present invention overcomes the problems that accompany the use of ramps to load and unload transducer carrying sliders in rigid magnetic disk data storage devices. The tracks in the region where the slider loads and unloads are read and the errors recorded following each slider loading operation. One technique is to track the error increase and identify imminent device failure when the rate of error increase during a given number of the most recent slider load cycles exceeds a threshold value. In another mode, a dedicated sequence of tracks is recorded at an increased linear density to assure that read errors occur to enable a more effective comparative evaluation. This makes possible a two stage evaluation, a first threshold number of errors indicative of degrading performance which initiates lower actuator velocity to inhibit further degradation and a second threshold error quantity that indicates imminent catastrophic failure and triggers a warning to the system user. To make the analysis more meaningful, certain errors may be ignored, such as simpler errors or the full number of errors in a cluster that may be the result of a single event.
