    摘要： A first variable resistor (5) is connected between a first terminal (7) and a third terminal (9) and increases/reduces its resistance value in accordance with the polarity of a pulse voltage applied between the first terminal (7) and the third terminal (9). A second variable resistor (6) is connected between the third terminal (9) and a second terminal (8) and increases/reduces its resistance value in accordance with the polarity of a pulse voltage applied between the third terminal (9) and the second terminal (8). Given pulse voltages are applied between the first terminal (7) and the third terminal (9) and between the third terminal (9) and the second terminal (8) to reversibly change the resistance values of the first and second variable resistors (5, 6), thereby recording one bit or multiple bits of information.

    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 timing recovering apparatus comprises an equalizer for equalizing a digital data signal subjected to interleaved NRZI such that the digital data signal has partial response (1, 0, -1), two comparators for comparing the equalized data signal with two different reference levels, two phase comparing portions for detecting phase difference between the outputs of the comparators and a reproduced clock signal separately, an adder for summing the outputs of the phase comparators, and a VCO for generating the reproduce clock signal in accordance with the output of the adder. This timing recovering apparatus performs phase comparing with two different phase comparators and PLL control is performed on the sum of the outputs of the two different phase comparators, so that the clock signal is not affected by data pattern of the data signal. An automatic slice apparatus comprises the equalizer for equalizing a digital data signal subjected to interleaved NRZI, and two comparators supplied with reference levels, and the timing recovering apparatus, detects amplitude of the output of the equalizer in response to the reproduced clock signal to compensate the reference levels.
