20090128942 | Method for Determining Wear of a Data Storage Medium and Data Storage Device - The invention relates to a method of determining wear of a data storage medium actively by performing a read operation on the data storage medium and detecting a read signal, comparing the read signal to at least one wear threshold; and determining a wear level of an area of the data storage medium based on the comparison. The wear threshold is lower than a detection threshold, wherein the detection of the read signal above the detection threshold indicates the presence of stored data. | 05-21-2009 |
20100182892 | DATA STORAGE MEDIUM AND METHOD FOR SCANNING A STORAGE MEDIUM - A data storage medium stories data in the form of marks, said marks being written and/or read by an array of probes. The storage medium further includes a plurality of data fields, each field including an area of the storage medium which, in use, is scanned for reading and/or writing by an associated one of the array of probes. The data fields include operational data fields having operational data for operating said scanning stored herein, wherein the operational data fields are arranged in a plurality of clusters, each cluster including a plurality of adjacent operational data fields. The invention also provides a method of scanning the data storage medium with the probe array, in which a target data field is determined and an operational data cluster closest to the target data field is selected and the operational data stored therein is used to control parameters of the scanning. | 07-22-2010 |

20120075037 | APPARATUS AND ASSOCIATED METHODS - In one or more embodiments described herein, there is provided an apparatus comprising input and output waveguides, and a carbon nanotube array. The array is positioned to electromagnetically couple the waveguides. The array has a slow-wave factor associated therewith, the speed of propagation of waves through the array being determined by this slow-wave factor. The array also has a first interface region. The apparatus further comprises a tuning element positioned to oppose the first interface region of the array to define a tuning distance. The slow-wave factor is affected by this tuning distance, and the tuning element is configured to be movable with respect to the first interface region so as to vary this tuning distance and thereby control the speed of propagation of waves through the array. | 03-29-2012 |
