摘要： PURPOSE:To provide recording signals which are suitable to a high density recording by generating an information string that is generated by adding one control bit to a (k) bit impressed information string in order to add pilot signals. CONSTITUTION:This device is provided with a circuit 1 which adds control bit 0 or 1 to an impressed information string, a modulator 2, a circuit 3 which adds a known information train to the information train, a circuit 4 which performs a frequency analysis of the train, a memory 5 which temporarily stores the analysis result, a comparator 6, a circuit 7 which selects an output and a memory 8 which records plural modulated strings. Zero or 1 control signal is added to the impressed information string for every 24 bits by the circuit 1, the string is inputted to the I-NRZI modulator 2 and outputted at an Fch frequency as a modulated string with a word which has 25 bits. On the other hand, the generated pilot frequency is 1/150 of the Fch and corresponds to equivalent of six words (150divided by 25=6) where one word has 25 bits. A spectrum of Fch/150 frequency is obtained against all 26 combinations of 0 and 1 control bits which are added to one period of pilot signals, store them in the memory 8 and pilot signals are generated by obtaining a largest modulated string which has a largest power and by impressing it to the output.

摘要： PURPOSE:To secure a stable S/N and also to improve the performance and reliability of a device by using the signal reproduced from one of two heads which has the narrower head track width, for the production of an ATF error signal. CONSTITUTION:When double azimuth heads 12 are used for the magnetic recording/reproducing device in which four-frequency pilot system is adopted for an ATF servo, the signal with maximum level can be reproduced by either of both heads by using the signal reproduced from one of two heads which has the narrower head track width, for the production of ATF error signal. Also, in the case the regenerative signal inputted to an ATF error signal detection part is limited to either one of the heads A, B like a two-frequency pilot system, the signal with maximum level can be reproduced by either of both heads by setting the head track width of the head outputting the regenerative signal to the ATF error signal detection part to be the same as or narrower than the head track width of another head. As the result, the stable S/N is secured and the reliability of the device is improved.
