摘要： A surface of an upper rotary drum of a video tape recorder is machines such that it has a surface roughness in a range from 1 .mu.m to 2 .mu.m so as to enable a releasing of air on the upper rotary drum surface uniformly whereby a thickness of an air film between a magnetic tape and a head is uniformly reduced without affecting the tape running. The surface may be grooved concurrently with the roughened surface. A window is formed in rotary drum for receiving at least one magnetic head.

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.
摘要翻译：本发明涉及一种用于诸如VTR的磁记录和重放装置中的旋转鼓装置，特别涉及安装在旋转滚筒上的磁头和飞行擦除头的结构。飞行擦除头和记录头的设计几乎相同，其擦除频率设置为低于记录频率，目的是消除旧记录而不是完全擦除，而飞行擦除头的方位角为0度并且用于以接近设备的最大记录频率的频率擦除旧记录，允许擦除任何特定信道的记录。实际上相同形状的飞行擦除头和记录头减少了制造成本。比记录频率低的擦除频率会影响磁头分离，并且可以无需特殊的屏蔽措施来安装飞行擦除磁头，以防止诸如串扰的故障性能。旧的记录可以容易地擦除或消除，并且由于方位角损失，由飞行擦除头部印刷的信号不被拾取。记录频带内的擦除信号频率几乎不产生串扰。

摘要： A disk is moved between disk cartridges without being in touch with the disk. Therefore, movement of the disk between the disk cartridges is carried out via a disk holder. Further, when the disk is moved between the disk cartridges, disk information of the cartridge is also moved simultaneously. Accordingly, the disk information held by the disk cartridge is provided at a disk holder portion and the disk information can be read by other disk device. Further, the disk holder is provided with a region representing information of the disk. When it is made to be a label region, in moving the disk between the disk cartridges, also the disk information held by the disk holder can simultaneously be moved. Further, even when the disk cartridge incorporates the disk, the content of the disk can easily be recognized via the disk holder. Further, a user can arbitrarily write or erase content of the disk to or from the label region, the disk is recognized easily and easiness of use is considerably promoted.
