A system and method for selective recording of information uses sequential pattern matching of statistical vectors which characterize incoming time-based information to identify previously marked information within an incoming information stream. The system and method generate a signal to control a recording device to either elide the previously marked information from the recording, or to begin recording once the previously marked information is identified, depending upon the current mode of operation. The system and method may be utilized to omit recording of unwanted information, such as commercials in a television broadcast, or to automatically locate desired information on any of a number of available information channels without a priori knowledge of the occurrence time or channel of the information.

Asynchronous servo RRO detection employing interpolation
ActiveUS7092462B2Filamentary/web carriers operation controlRecord information storagePeak valuePeak detection
A repeatable read-out (RRO) detector employs one or more digital interpolators to interpolate asynchronous sample values that represent RRO data. The asynchronous sample values are read from a recording medium and generated by an A / D converter at a symbol rate, and the interpolators generate interpolated samples at at least one time in between the asynchronous sample value times. Each interpolated sample corresponding to some phase relative to that of the sample values generated by the A / D converter. The RRO detector receives 1) the asynchronous samples at symbol rate and 2) the interpolated samples to efficiently detect the encoded RRO data. An RRO address mark indicates when detection of encoded RRO data starts, and is employed to select those samples suitable for RRO data detection. Detection of the RRO address mark employs peak detection among filtered asynchronous and interpolated samples. The process of peak detection adjusts the current best phase for sample selection. When the RRO address mark is found, the corresponding best phase corresponds to either asynchronous sampled values or interpolated samples that are subsequently selected for RRO data detection, termed best samples. Once the best phase is selected, the RRO data detector uses that information along with RRO encoding constraints to decode the encoded RRO data from the best samples.

A disk drive with switchable power levels for the heaters in the sliders is disclosed. The invention includes a switch for the electrical circuit of each heater which selects between two or more voltages to apply to the power control element and the heater with at least a high and a low voltage option. The heater power control circuit dissipates a certain amount of heat as a part of the control process. By having a low voltage option the disk drive can save power and reduce the amount of heat dissipated by the heater control circuit when high power is not required. The programmable switch is controlled by the drive control system. The high power setting can be used during manufacturing testing or otherwise if higher heater power is needed. The low power setting is used for normal operation or to save power.

InactiveUS6876511B2Filamentary/web carriers operation controlTrack finding/aligningComputer sciencePosition shift
A detector detects, in read data, a servo address mark of a type indicated by a register. Every time a SAM is detected during a self servo process, a CPU carries out tracking control in accordance with corresponding servo data. The CPU causes a head to write a corresponding type of additional servo data item in a disk at a position offset from the position of servo data containing the detected SAM, by a predetermined distance in a circumferential direction of the disk. Every time sets of servo data, each consisting of various types of data items, are written in the disk, the head is moved by a predetermined pitch in a radial direction of the disk.

InactiveUS7082007B2Reduced and minimized amountAccurate informationFilamentary/web carriers operation controlTrack finding/aligningTrack densityTransducer
A disc drive includes a transducer having a separate element for writing information and a separate element for reading information to and from the disc. In a disc drive designated to read and write long sequential records, the track misregistration budget is reduced to account for previously written tracks not being encroached on one side. An initial track is written. Subsequent tracks are written after a seek in one direction. The subsequent track is written so that the initially written track is overwritten to one side and leaves a track having a width substantially equal to the width of the read element. Records can be written into data bands of a selected number of tracks. A guard band is left between groups of data bands so that data on tracks in subsequent data bands are not overwritten.

Excellent magnetization switching of a magnetic recording medium is promoted in microwave assisted magnetic recording to provide a highly-reliable high-density information recording device. A receded section from an air bearing surface is arranged at an end section in a write track width direction on an FGL laminate film for generating a high-frequency field. Alternatively, a cross section of the FGL laminate film (plane perpendicular to the direction of the flow of the electric current) has an inverted trapezoid shape or has a structure in which the area of the cross section increases with distance from the main pole. Since an excellent recording pattern is formed on the recording medium, areal recording density in the information recording device can be increased, and the reliability can be improved at the same time. As a result, the cost can be reduced.
