Magnetic recording/reproducing apparatus

Abstract

A magnetic recording/reproducing apparatus for recording data on a medium, for checking the recorded data and for retrieving any of the recorded data comprises a data reproduction device for reading data from a medium includes a conversion device for converting the signals for the reproduced data from the data reproduction device into read data pulses, a variable frequency oscillator for producing read data and window data out of the read data pulses from the conversion device and a follow-up characteristics switch device for switching the follow-up characteristics of the variable frequency oscillator from a narrow range option suitable for data checking to a wide range option suitable for data reproduction. With such an arrangement, a high level of quality of recorded data can be maintained, a wide range of compatibility of recording media is ensured and the rate of issuing error messages due to ISVs that can interrupt the operation of the apparatus is reduced.
