摘要： A servo system for controlling the rotational speed of a rotating body or the moving speed of a moving body to be a desired speed. The system comprises a voltage source which generates at least two predetermined voltages, a comparator which compares a voltage of an AC signal containing a speed information of the moving body with each of the voltages generated by the voltage source and outputs at least two output signals in each half period of the AC signal, a counter for counting reference clock signals, a memory for storing a count value of the counter when the comparator outputs each of the output signals, a processor for producing a speed error signal from the count value stored in the memory, and a driver for supplying a driving power to the moving body in accordance with the speed error signal thereby to keep a desired speed of the moving body. Further, an error compensator may be provided for compensating a voltage shift of the predetermined voltages.

摘要： A system includes electronic equipment, an information processing device and a server device. The electronic equipment sends first address change confirmation information containing first address information to the information processing device. The information processing device sends second address change confirmation information obtained by writing second address information in the received first address change confirmation information. The server device determines that the first address information and the second address information, which are contained in the received second address change confirmation information, agree with each other, and updates the address information to new one when the first address information and the second address information do not agree with each other. With such a system, electronic equipment can hold up-to-date address information of the information processing device with extremely light processing at the side of the server device and with small load of communication.

摘要： At least three heads are mounted on a rotary drum. Between the first and third heads which are located in close proximity to each other and have different azimuth angles, a minute height difference is formed in the rotation shaft direction of the rotary drum. Signals of a plurality of data rates are recorded and reproduced by using the first and second heads or the first and third heads. Two heads having the same azimuth angle are disposed on the rotary drum so as to be opposed each other at a central angle of 180°. In search speed reproduction, search data are reproduced by the two heads. Tracks are divided in the unit of plural tracks so as to form track sets. Search data areas of each track set are disposed at a position of each track which is separated from the edge of a tape by a predetermined distance. In search speed reproduction, the phases of the tracks and the heads are controlled, and all effective data of the search data areas are reproduced by plural scans of the heads.

摘要： A recording apparatus for recording digital signals to plural tracks formed sequentially on a tape using plural heads includes a first selector for selecting the first through n track sets, continuous tracks within the plural tracks formed on the tape. A disposer disposes the first through k separated high speed reproduction data areas to the same positions in each of the m tracks comprising the first through n track sets. A first recording unit records the same high speed reproduction data to the same track position in at least the tracks having the same azimuth within the m*k high speed reproduction data areas belonging to the same track set. A second selector selects the n+1 through n+N, each track set comprising M tracks selected from among the tracks to which the high speed reproduction data areas are not disposed. A second disposer disposes a continuous very-high speed reproduction data area to the same position in each of the M tracks forming the n+1 through n+N track sets. A second recorder record the same very-high speed reproduction data to the M very-high speed reproduction data areas belonging to the same track set within the M*N very-high speed reproduction data areas belonging to the n+1 to n+N track sets.
