摘要： System and method for generating a Position Error Signal (PES) reference curve in data storage devices are provided. The method includes scanning a distance of at least one Track Pitch (TP) in a cross-track direction in each servo-burst along a predefined path. One or more TPs in each servo-burst are scanned with a read head. The method further includes, calculating a plurality of samples of each differential signal. A differential signal corresponds to a first read-back signal and a second read-back signal. Thereafter, a plurality of normalized signals are determined. A normalized signal is determined by dividing each sample of the differential signal with a normalization constant. The plurality of normalized signals are combined to generate the PES reference curve.

摘要： Methods and apparatus are provided for controlling writing and reading of data in an array of A storage fields of a probe-based data storage device in which data is written to and read from the array of storage fields by a corresponding array of probes. One method provides error-tolerance by exploiting the inherent parallelism of the probe storage array. A user data block to be written to the A-field array is first coded to produce a plurality of C-byte codewords, such that r·C=k1A where r is the number of codewords and k1 is an integer greater than or equal to 1. A sub-blocks of k1 bytes are produced from the codewords by selecting successive bytes of each sub-block cyclically from the r codewords. The A sub-blocks are then written via respective probes to the corresponding storage fields of the storage field array.

摘要： Methods and apparatus are provided for recording/reproduction of data in a probe-based data storage device (1) in which application of a write signal causes formation of an indentation in a storage surface (5) by a probe of the device (1). Instead of storing information in the presence or absence of indentations on the storage surface as is conventionally done in such devices, information is stored in the form of grooves of variable length separated by lands of variable length. More particularly, a sequence of n>1 successive bits of a first value (typically “1's”) in a recording signal is recorded by applying a series of write signals at respective probe-positions on the storage surface (5). These probe-positions are spaced at w≦M, where M is the indentation merging distance, so that the resulting indentations merge to form a groove in the storage surface (5) spanning n readback sample positions. The readback signal corresponding to the recording signal is sampled at timings corresponding to the readback sample positions to recover the original bit sequence. High density recording is provided because the readback sample position spacing s here satisfies s

摘要： Methods and apparatus are provided for controlling writing and reading of data in an array of A storage fields of a probe-based data storage device in which data is written to and read from the array of storage fields by a corresponding array of probes. One method uses the concept of sub-arrays to provide variable-rate read/write operation. Input data blocks are received for writing to the A-field array, each input data block being writable in A/k0 storage fields where k0 is an integer ≧2. For successive groups of k0 blocks, the k0 blocks are written to respective sub-arrays, each of A/k0 storage fields, of the storage field array by selectively writing at one of a series of rates, ranging from 1 block at a time to k0 blocks at a time, in dependence on a desired data write-rate. The blocks can also be read from the sub-arrays by selectively reading at one of a series of rates, ranging from 1 sub-array at a time to k0 sub-arrays at a time, in dependence on a desired data read-rate.
