Abstract: In a data recording apparatus, the period of the first clock signal corresponding to the record data is multiplied by the stated numeric corresponding to the transfer rate with the clock signal forming structure, so that the second clock signal is formed. And, on the basis of the record data and the second clock signal, the recording current corresponding to the transfer rate that is formed by highlighting the high-frequency component in accordance with the transfer rate and by limiting the band in accordance with the transfer rate is generated with the recording current generating structure. Then, the recording data is recorded on the recording medium with the recording structure on the basis of the recording current, therefore, even if the transfer rate varies, it is able to equalize highlighting operation of high-frequency component of the recording current and to equalize band limitation so as to keep the frequency characteristics approximately constant.

Abstract: A magnetic recording and reproducing apparatus amplifies a current representing a recording signal reproduced from an information signal recorded on a magnetic tape, suppresses low frequency components of the current amplified signal, then amplifies a voltage representing the suppressed signal. The voltage amplified signal is supplied from a primary winding of a rotary transformer inside a drum to a secondary winding of the rotary transformer disposed outside the drum, and then its low frequency components are emphasized. This avoids the problems of an inadequate S/N in the low frequency components of the output of a voltage amplifier, and difficulty in providing a high voltage signal from a current amplifier. The emphasized signal is supplied to one of a plurality of equalizing circuits that respectively equalize a signal reproduced at one of a plurality of frequencies.

Abstract: A magnetic sensor is disposed in an opposing relationship to a rotating magnetic head device with a magnetic head mounted thereon and placed in noncontact therewith so as to fall outside a lap angle .alpha. of a magnetic tape. The magnetic sensor is used as a part of oscillating elements of an oscillator circuit. By noting that a magnetic resistance of a magnetic circuit at a rotational position where the magnetic head faces the magnetic sensor changes according to the degree of extension of the magnetic head from the surface of a drum, and taking the change in magnetic resistance as a variation in oscillating frequency, the rate of wear of the magnetic head is measured. Since the change in magnetic resistance is taken as the variation in oscillating frequency, the degree of extension of the magnetic head, i.e., the rate of wear of the magnetic head can be measured with high accuracy.
