    摘要： Methods and apparatus are provided for recording input data in q-level cells of solid-state memory (2), where q>2. Input data words are encoded as respective codewords, each having a plurality of symbols. The coding scheme is such that each symbol can take one of q values corresponding to respective predetermined levels of the q-level cells, and each of the possible input data words is encoded as a codeword with a unique sequence of relative symbol values. The symbols of each codeword are then recorded in respective cells of the solid-state memory by setting each cell to the level corresponding to the recorded symbol value. Input data is thus effectively encoded in the relative positions of cell levels, providing resistance to certain effects of drift noise.

    摘要： A device including a first part and a second part, one of which is a cantilever, the first and second parts being connected to each other and movable relative to each other. The device includes a magnetic element arranged on the first part and configured to provide a magnetic field. The device further includes a magnetization device arranged on the second part and configured to provide an actuation magnetic field which interacts with the magnetic field of the magnetic element, thereby causing or suppressing relative movement of the first and second parts. A scanning system including such a device is also described.

    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.
