摘要： A loading unit for a disc cartridge includes a cartridge holder movably supported relative to a chassis. The cartridge holder is moved towards a recording and/or reproducing device for recording and/or reproducing information signals on or from a recording medium housed within the disc cartridge. The cartridge holder is configured to hold the disc cartridge inserted therein and has an engaging recess and an insertion detector. The insertion detector is moved in response to the disc cartridge being inserted into the cartridge holder. A stop mounted on the cartridge holder has a retention portion for retention by the chassis and an engaging protrusion for engagement with the engaging recess of the disc cartridge. The stop is slidingly contacted with the chassis in conjunction with movement of the cartridge holder towards the recording and/or reproducing device. The stop is inhibited from movement by the insertion detector when a disc cartridge is not inserted into the cartridge holder and the retention portion is engaged by the chassis. The stop is released from inhibition of movement when the disc cartridge is inserted into the cartridge holder and the insertion detector is moved, thereby disengaging the retention portion from the chassis, whereby the stop engages the engaging protrusion with the engaging recess in the disc cartridge.

摘要： The mechanism for loading and unloading a disk cartridge uses two sliders (one on each side of a base plate), which move in opposite directions under the influence of a tiller. Each slider has a slot to receive one of the two lifting pins provided on the cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle. As the lifting pins travel along their respective slots, the lifting and lowering of the disk is accomplished in such a manner that the disk hub is peeled from the spindle magnet rather than being lifted vertically off the spindle. This reduces the peak force required to break the magnetic clamp force between the spindle magnet and the disk hub. In this system, the dust door is attached to the cartridge receiver, and the label end of the loaded cartridge remains visible when the disk is loaded. This system may include a bias coil assembly rotatably mounted on an arm so that the bias coil assembly may be loaded into or extracted from the disk cartridge and placed out of the travel path of the disk cartridge. The rotation of the bias coil arm is effected by one of the sliders.

摘要翻译： 用于装载和卸载盘盒的机构使用两个滑块（在底板的每一侧上一个），其在分蘖的影响下在相反方向上移动。 每个滑块具有一个槽，用于容纳设置在盒式磁盘接收器上的两个提升销中的一个。 滑块的运动沿着狭槽驱动提升销，从而根据耕作机的旋转方向升高或降低料盒接收器。 接合在S形槽中的提升销的滑动运动由此将盘卸载或替代地将盘装载到驱动主轴上。 当提升销沿其相应的槽行进时，盘的升降是以这样的方式实现的：盘毂从主轴磁体剥离，而不是垂直地离开主轴。 这样可以减少断开主轴磁铁和磁盘轮毂之间的磁夹紧力所需的最大力。 在该系统中，防尘门安装在墨盒接收器上，并且装入墨盒的标签末端在加载磁盘时保持可见。 该系统可以包括可旋转地安装在臂上的偏置线圈组件，使得偏置线圈组件可以被装载到盘盒中或从盘盒中取出并且被放置在盘盒的行进路径之外。 偏置线圈臂的旋转由滑块之一实现。

摘要： A recording/reproducing apparatus incorporates a beam splitter arrangement that directs stray reflected light away from the incident and exit paths. The beam splitter is arranged such that refracting surfaces are angled away from a 45 degree angle by an amount corresponding to a refracted angle of an incident beam. The entire beam splitter is arranged in the recording/reproducing apparatus such that the refracted beam is refracted by a predetermined angle based on the known refractive index of the beam splitter prisms and the orientation of the beam splitter.

摘要： Disclosed is magnetoptical disc apparatus for recording information in magnetoptical recording medium using a floating type magnetic head. The apparatus includes a floating type magnetic head for applying a modulated magnetic field to the medium, a leaf spring for supporting the magnetic head floatably above the medium, a retreating mechanism for moving the magnetic head from a position at which the magnetic head can contact the medium and a limiting device for limiting a deflection of the leaf spring when the retreating mechanism moves the magnetic head from the above-mentioned position. The driving stroke needed for moving the magnetic head can be reduced, and as a result, the retreating mechanism can be made small in size.

摘要： A magnetic head loading/unloading apparatus has a head arm being maintained in either a loading state or an unloaded state by means of a permanent magnet. The head arm has a magnetic head on one end thereof, and is fixed on an end of a first yoke. A second yoke is arranged parallel to the first yoke, and is rotatable on the first yoke. A touching member is fixed on the second yoke, the touching member pressing a bottom surface of the head arm so as to elastically deform the head arm so that the magnetic head is positioned in an unload position. A permanent magnet is provided on the first yoke and a coil is provided on the second yoke. When the second yoke is moved to a first position, the head arm is elastically bent by a pressing force exerted by the contacting member so that the magnetic head is positioned in an unload position. When the second yoke is moved to a second position, the contacting member is apart from the head arm so that the magnetic head is in a load position. The second yoke is maintained in either the first position or the second position by the attracting force generated by the permanent magnet.

摘要： A holder holds a mini-disc cartridge and mounts the disc on a turntable. An optical pickup transport holding an optical pickup for applying a laser spot to a signal record track of the disc is movably supported by a guide rod. A magnetic head contacts the disc and applies a magnetic field to the back surface of the disc where the laser spot is applied. A switch judges whether the data record to the disc is to be permitted. The magnetic head is pushed against the disc only when the mounted disc is permitted to record data and the data record is to be performed.
