A head drum assembly of a magnetic recording and reproducing apparatus includes a fixed drum secured to a shaft and a rotary drum rotatably fitted on the shaft to be opposite to the fixed drum. A motor rotor is supported in the rotary drum. A stator is installed on the fixed drum to be opposite to the motor rotor. A yoke is secured to the fixed drum so that a predetermined air gap is provided between the stator and the yoke.

A spindle motor assembly and an information recording/reproducing device having the same. The spindle motor assembly includes a spindle motor (110), a turntable (120) to be rotated by the spindle motor together with a disk placed and supported thereon, and a support pad (140) provided on the turntable to support a lower surface of the disk; wherein the support pad is provided at a point that corresponds to 2/3 of a diameter of the turntable with respect to a rotation center of the disk.

A recording medium cover locking device of the image photography apparatus according to the embodiment of the present invention comprising a recording medium cover, that can open or close, provided in the image photography apparatus; a lock member for locking or unlocking an opening/closing operation of the recording medium cover; and a restriction unit for restricting a movement of the lock member to inhibit the recording medium cover from being opened white the image photography apparatus is operating in a specific mode. Accordingly, in the image photography apparatus employing the optical disk as the information recording medium, the recording medium cover is not opened while the image photography apparatus is operating in the specific mode, and so it is possible to prevent the optical disk from being damaged or disturbed while recording.

The magnetic tape guiding system of a tape recorder transport system has a supply reel pole base assembly (235) having a slant pole (235) with a first guide unit (238) having portions formed at both ends of the slant pole (235) to function as a conventional roller for regulating upward and downward movement of the upper and lower edges of a moving magnetic tape (20), and a tension pole assembly (231) having a tension pole (233) with a second guide unit (234) having portions formed at both ends of the tension pole (233) to function as a conventional impedance roller for regulating upward and downward movement of the upper and lower edges of the moving magnetic tape (20). This arrangement can thus achieve 2-dimensional plane-traveling of the magnetic tape while also reducing the number of the parts of the guiding system
摘要:
The main chassis (110) of a tape deck has a sloped projection (130) onto which a head drum (20) is mounted. This avoids the need for a separate head mounting structure. Additionally, pole base guide rails (141, 142) may also be formed integrally with the main chassis (110). The preferred method of forming the integrated main chassis (110) is pressing.

A tape guide device for a magnetic recording/reproducing apparatus includes a pole base assembly (50) to guide a tape, supplied from a supply reel and passed through a predetermined path, to move it horizontally to a read surface (41a) of a head drum (41). The pole base assembly (50) includes a pole base (51) and a pole unit (60) including a spiral flange (70) having an end face parallel to the read surface (41a) of the head drum (41), to guide the tape approaching the head drum such that it is inclined at a predetermined angle and aligned in the horizontal direction to the read surface (41a).
