Abstract: The optical disk recording and reproducing apparatus includes (1) an optical head, (2) a linear motor for moving the optical head in a radial direction of an optical disk (3) a position detection sensor for detecting a position of the optical head, (4) a speed detector for detecting a moving speed of the optical head, (5) a CPU for calculating an access distance, based on the present position of the optical head and a designated track, in accordance with an output of the position detection sensor, (6) a ROM for generating a table value for an adjustable target speed of the optical head in accordance with the distance, (7) a speed offset memory for storing a speed offset value for adjusting an error in the access distance, (8) a coarse access control device for controlling the linear motor to move the optical head, based on an error signal obtained from a difference between the adjustable target speed and an actual speed of the optical head detected by the speed detector, before the optical head reaches a switching point located just before the designated track in a coarse access, the adjustable target speed being obtained by adding or subtracting the speed offset value stored in the speed offset memory to or from the table value generated by the ROM, and for setting the adjustable target speed to "0",   after the optical head passes the switching point, and (9) a fine access control device for judging whether the optical head is positioned on the designated track upon completion of the coarse access, and for performing a fine access, controlling the linear motor to move the optical head to a vicinity of the designated track, when the optical head is not positioned on the designated track. With such an arrangement, the accuracy of the coarse access can be improved and time required for the coarse access can be reduced. Another optical disk recording and reproducing device further includes a speed offset value correcting device for correcting the speed offset value released in accordance with an access error in the coarse access when a distance between a position of the optical head and the designated track is more than a reference value upon completion of the coarse access. The speed offset value is accordingly corrected by a learning control, and this further improves the accuracy of the coarse access, saving the overall access time.

Abstract: Digital data produced by a document scanner (15) or other data source is sequentially stored in a memory (40). A remote data receiver (45) generates requests for data (43) causing communication of the data (44) from the memory (40) in the same sequence in which it was stored but at a rate substantially asynchronous with respect to the rate of scanner (10) data production. Data (19) from the scanner (15) is sequentially loaded into the memory (40) in recycling sequences until there are no available memory storage sections (0-N). The scanner (15) is then caused to stop scanning and to cease data production until transfer of data from a memory (40) storage section to the remote receiver (45). The scanner 15 is thereafter enabled so as to resume with production of the next data following that which was last loaded into the memory (40). For a scanner, the data interruption and resumption is obtained by stopping and repositioning of the scanner bar (27) relative to the document (11).

Abstract: A first circular ring of a given inductance is coupled to second and third circular rings by a plurality of equally spaced parallel rods to form a birdcage coil. The second and third rings have a combined inductance the same as that of the first ring and are located adjacent to each other at an end of the rods opposite the first ring. A tune-detune circuit is located at the end of and couples each of the rods to the second and third rings. This circuit includes parallel capacitances whose combined value is the same as the capacitance coupling the rods to the first ring to selectively tune the coil to a given radio-frequency. PIN diodes selectively rf couple the parallel capacitances respectively to the second and third rings. Direct current diode bias voltages are applied to the second and third rings which act as busses for the bias voltages. The second and third rings are split in half and capacitively coupled to permit applying relatively higher (DC) bias voltages to the diodes. The coil is divided into upper and lower halves with open space between the rods of the upper half to permit access to a patient's head and for patient comfort during examination.

Abstract: A method and circuitry are described for sensing the clearance between a magnetic transducer (10) and a moving magnetic recording medium (9) in a magnetic disk or tape storage system or alternatively sensing the degree of magnetic instability of a magnetic transducer in such a system. Magnetic transitions prewritten on a preselected area of the medium are read to obtain a readback signal. The width of said signal is sensed at a predetermined amplitude level which is a preselected percentage of its base-to-peak amplitude to provide a voltage corresponding to the width of said signal at said level. The voltage is proportional to the width of the readback signal divided by the time period between successive transitions of identical polarity, so as to provide a measurement of clearance or degree of magnetic instability that is independent of the relative velocity between said transducer and medium. 
     The voltage is digitized and compared to a prestored digital reference value. If the clearance is not within a preestablished acceptable range, a desired control operation is initiated, such as stopping movement of the medium. the preselected percentage can vary between 10% and 90%. However, when measuring transducer-medium clearance the percentage is preferably 45%-55%; whereas when measuring degree of instability, the percentage is preferably 30%-35%.
