    摘要： An apparatus for recording an information signal with rotary heads in each of a plurality of areas extending in the longitudinal direction of a tape-shaped recording medium is arranged to reproduce with the rotary heads a signal already recorded in a first area among the plurality of areas; and to record the information signal in the second of the areas while performing tracking control over the rotary heads by using the reproduced signal obtained from the first area.

    摘要： In an apparatus for recording a data sequence including main binary data of an (m X n) number of bits formed by sampling a main information signal and a plurality of subordinate binary data of also an (m X n) number of bits respectively carrying additional information of varied kinds, recording tracks are formed one after another with data which includes the main binary data representing the main information signal sampled within a given period of time and the plurality of subordinate binary data recorded in each of the tracks; and recording is performed in such a manner that, among the plurality of subordinate binary data, the meaning of information carried by a second n number of bits varies according as the condition of the data varies between a case where l-adic numerical data is arranged to be formed by a first n number of bits within the plurality of subordinate binary data and another case where irregular data is formed there as the l-adic numerical data cannot be formed by the first n number of bits (n and m being integers, respectively, and l being an integer not exceeding 2.sup.n).

    摘要： A data processing device for processing data including a first data sequence indicative of the amplitude of an information signal and a second data sequence each data of which indicates the error rate of each data of the first data sequence. When each data of the second data sequence continuously shows a high error rate of a consecutive number of data of the first data sequence more than a predetermined number, the device generates data of values which are 1/a.sup.k (wherein "k" represents an integer between 1 and "n"; "a" a real number larger than 1; and "n" an integer at least 2) of a data of the first data sequence which has a low error rate and is located before or after the consecutive high error rate data of the first data sequence. The device performs data processing for muting the information signal by using these data.

    摘要： In an apparatus for recording an information signal on a recording medium forming many parallel tracks on the medium and for reproducing the information signal from the medium, a tracking control system is arranged to record a pilot signal of a given frequency along with the information signal in the first of the many tracks; to have the pilot signal also recorded in second and third tracks adjoining the first track on both sides thereof but at pilot signal phases shifted from the pilot signal phase of the first track to equal degrees in the directions opposite to each other at parts of the second and third tracks aligned perpendicularly to the longitudinal direction of the first track; and, in reproducing the information signal, the position of the recording medium and that of a reproducing head relative to each other are controlled on the basis of the pilot signal of the given frequency reproduced by the reproducing head from the first track along with the information signal.
