    摘要： In a magnetic recording and reproducing apparatus, a reproduced output (V2) obtained from a magnetic tape (3) by means of a rotary head (2) mounted within a drum is current-amplified (6), and a low frequency component thereof is suppressed (11). The reproduced output is thereafter voltage-amplified (12A) and then transmitted outside of the drum via a rotary transformer (12B). The suppression of the low frequency component is compensated by de-emphasis means (12C) arranged outside of the drum. A number of equalising circuits (15A to 15F) may receive an output of the de-emphasis means (12C), the equalising circuits being so arranged as to equalise a higher frequency component of the output in an order of frequencies of the equalising circuits that increases in accordance with the proximity of the equalising circuits to a terminating resistance (R10).

    摘要： In a data recording apparatus, a relative speed of a magnetic head 4 to a magnetic recording medium 5 is changed according to data rates of information data, on recording the information data on the magnetic recording medium by the magnetic head so that said information data is recorded with identical magnetized patterns on the magnetic recording medium even with different data rates of the information data. A control means generates a control signal (SRT) according to the data rates of the information data and a frequency characteristic processing means (12, 13; 22, 23) processes the information data to cause the frequency characteristic of the information data to have a frequency characteristic predetermined according to the control signal. Thereby magnetized patterns on the magnetic recording medium are identical with any data rates and this enables compatibility of record and production of the information data to be kept between different data rates.
