    摘要： This invention relates to a rotary drum device used in magnetic recording and playback apparatus such as VTRs, and particularly to the structure of a magnetic head and flying erasure head mounted on the rotary drum. The flying erasure head and recording head are of virtually same design, with the erasing frequency being set lower than the recording frequency with the intention of obliterating the old record instead of erasing it completely, and the flying erasure head has an azimuth angle of 0.degree. and operates for erasing the old record at a frequency close to the maximum recording frequency of the apparatus, allowing the erasure of record of any particular channel. The flying erasure head and recording head of the virtually same shape reduce their manufacturing cost. The erasing frequency lower than the recording frequency effects the head isolation, and the flying erasure head can be mounted without special shielding measures against such defective performance as crosstalk. The old record can be erased or obliterated easily, and the signal imprinted by the flying erasure head is not picked up because of the azimuth loss. The erasing signal frequency within the recording frequency band causes little crosstalk.

    摘要： An optical recording and reproducing system has an optical recording and reproducing head driving arrangement including an optical pick-up and has an optical recording medium provided between the recording heads. The optical recording and reproducing head is mounted on a rotating arrangement. The head scans tracks while a relative position of the recording medium and rotating arrangement is changed. Each track has an address recorded at the beginning of scanning and a hold signal at the end of scanning. The recording and reproducing heads are separated one track. The recording head makes recording while the reproducing head makes reproduction. In the recording or reproducing mode of operation, the track address is looked. If wrong, it is corrected. The hold signal is detected to operate a tracking device and focusing device. Scanning the next track is determined by the address before tracking is made for recording or reproduction.
