摘要： A pinch roller type tape drive for driving a magnetic tape on a VTR or the like comprises a capstan for driving the magnetic tape, and a pinch roller for pressing the magnetic tape against the circumference of the capstan so that the magnetic tape may not slip relative to the circumference of the capstan. The outermost layer of the pinch roller is formed of an elastic material having a hardness higher than that of rubber, which is used for forming the outermost layer of a conventional pinch roller. The pinch roller is capable of pressing the magnetic tape against the circumference of the capstan at a sufficient pressure without contacting the circumference of the capstan.
摘要翻译：用于驱动VTR等上的磁带的夹送辊式磁带驱动器包括用于驱动磁带的绞盘，以及用于将磁带压靠在绞盘的圆周上的夹送辊，使得磁带可能不相对滑动到绞盘的圆周。夹送辊的最外层由具有高于橡胶的硬度的弹性材料形成，其用于形成常规压紧辊的最外层。夹送辊能够以足够的压力将磁带压在绞盘的圆周上，而不会接触绞盘的圆周。

摘要： A magnetic head, a recording and/or playback method for a tape-type magnetic recording medium and a rotary magnetic head mechanism which are simple in structure and superior in contact characteristic with a tape-type magnetic recording medium. A window portion is formed in a concave manner on an outer circumferential face of a rotary drum along which a magnetic tape can be wrapped. A flat head of a width smaller than that of the window portion in the advancing direction is disposed in the window portion such that a pair of channels each in the form of an air gap are formed between the opposite leading and trailing ends of the flat head and the opposite leading and trailing ends of the window portion, respectively. The flat head has an exposed smooth flat face extending perpendicularly to a diametrical direction of the rotary drum and provided at a position retracted from the outer circumferential face of the rotary drum for being opposed to and fluidically interference with the magnetic tape. A head element for contacting and magnetically interference with the magnetic tape is disposed on the smooth flat face within a range within which the magnetic tape contacts with the smooth flat face.
