A write head (66) for writing information bits to magnetic storage media (94) comprises a first write pole (72) for producing a first magnetic field in a first direction and a second write pole (70) for producing a second magnetic field such that the combined field from the two poles lies either substantially along the first direction or in a second direction that is substantially orthogonal to the first direction. The second write pole includes a free layer (76) having magnetization controlled by spin transfer torque, and a first spacer (82) positioned between the free layer and the first write pole. The write head can further include a pinned layer (78) and a second spacer (80) positioned between the pinned layer and the free layer. A disc drive (10) that includes the write head and a method of writing to magnetic storage media that utilizes the write head are also included. |

This invention is a write-once near-field optical medium using a zinc oxide nano-structured thin film as the localized near-field optical interaction layer. This write-once near-field optical medium is a multi-layered body at least comprising: (a) a substrate of transparent material; (b) a first protective and spacer layer formed on one surface of the substrate, which is made of transparent dielectric material; (c) a zinc oxide nano-structured thin film which is capable of causing localized near-field optical interactions; (d) a second protective and spacer layer formed on the localized near-field optical interaction layer, which is also made of transparent dielectric material; (e) a write-once recording layer; (f) a third protective and spacer layer formed on the write-once recording layer, which is also made of transparent dielectric material. Ultra-high density near-field optical recording can be achieved by the localized near-field optical interactions of the zinc-oxide (ZnO) nano-structured thin film that is in the near-field region of the write-once recording layer. |

| patent | Writing and reading of data in probe-based data storage devices | Information and communications technology | 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... 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. |

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=k1.A where r is the number of codewords and k1 is an integer>=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. |
