摘要： A magnetic recording and reproducing apparatus includes: a recorder for recording information signals so as to form tracks obliquely on a magnetic tape, and for recording pilot signals so that the frequency may differ between different modes such as SP and LP; a reproducing head for reproducing recorded information; an error detecting circuit for comparing the level difference of pilot signals recorded in both tracks adjacent to the track to be scanned by there producing head and for outputting a tracking error signal; and a controller for controlling the feed of the magnetic tape so that the tracking error signal may be balanced. Preferably, in the LP mode, a pilot signal of a higher frequency than that used in the SP mode is recorded. In a tracking error detector for a magnetic recording and reproducing apparatus for detecting the pilot signal, the reproduced signals are sampled at a frequency at a common multiple of each pilot frequency, a pilot signal is detected, and a tracking error signal is output.

摘要： A tracking error detecting circuit is used in a magnetic reproducing apparatus for reproducing an information signal from tracks which are formed on a magnetic tape obliquely in a longitudinal direction of the magnetic tape. The tracks have selectively recorded thereon a pilot signal multiplexed with the information signal. The tracking error detecting circuit comprises: a rotating magnetic head scanning the tracks for reproducing the information signal on which the pilot signal is selectively multiplexed to obtain a reproduced signal; a comparator for comparing a level of the reproduced signal with a specified level and for issuing a binary signal representing a comparison result; and a level detecting circuit for detecting a level of the pilot signal contained in the reproduced signal from an output of the comparator.

摘要： A controller is configured to transmit a controller receiving terminal count, or the number of terminals with which the controller can communicate, to other terminals. Each of terminals operable as a controller other than the controller transmits a signal requesting controller change to the controller and acquires controller authorization if the number of terminals with which the terminal itself can communicate is larger than the controller receiving terminal count.

摘要： A network hardware device of the invention includes a reception section receiving data from a network, and outputting a reception completion signal, a timer section measuring a preset time, and a delay section generating an interrupt signal so as to notify a host CPU of completion of the reception. When the timer section does not measure a time, the delay section generates an interrupt signal upon reception of the reception completion signal. On the other hand, when the timer section measures a time, upon reception of the reception completion signal, the delay section generates an interrupt signal after the timer section measures a preset time.

摘要： A terminal best in the reception state for a signal from a controller of a neighboring network is determined as the controller of the own network, to ensure sharing of inter-network control. When the reception state is not good, a terminal worst in reception state is determined as the controller, to make the own network independent from a neighboring network and hence reduce interference of a reference signal and a control signal outputted from the own terminal with the neighboring network.
