摘要： A cartridge includes a shutter movably mounted along and on outside surfaces of a cartridge box for opening or closing a central hole and a head slit together, a slider for driving the shutter, and guide grooves provided outside a receptacle for a disk and serving to guide the slider. The shutter normally closes the central hole and the head slit to permit the cartridge to completely surround the disk, thereby preventing entry of dust from the outside. Even when the slider is broken by accident, the disk is immune from scratches to be constantly held in a good state since the slider is moved on the outside of the receptacle. Moreover, a drive for the shutter is provided forwardly of the center of the receptacle to enable increasing the recording capacity of the disk and miniaturizing the cartridge.
摘要翻译：盒式磁带包括可沿着盒式磁带盒的外表面可移动地安装的开关，用于打开或关闭中心孔和头部狭缝，用于驱动快门的滑块和设置在盘的插座外部并用于引导的引导槽滑块。快门通常关闭中心孔和头部狭缝，以允许盒完全围绕盘，从而防止灰尘从外部进入。即使当滑块被意外破坏时，由于滑块在容器的外部移动，因此盘不受划痕的影响，从而始终保持在良好的状态。此外，用于快门的驱动器设置在插座的中心的前方，以增加盘的记录容量并使盒小型化。

摘要： A disc cartridge has a casing having first and second apertures and first and second shutters slidably mounted to the casing for selectively opening and closing the first and second apertures. First and second shutter openers are respectively connected to the first and second shutters. Only the first aperture is opened using the first shutter opener when the disc cartridge is loaded in a standard specifications or existing recording and/or reproducing apparatus. When the disc cartridge is loaded in an optional specifications apparatus, both the first and second shutter openers are used to open the first and second apertures, respectively. A disc cartridge compatible with both new plural head recording and reproducing apparatuses and existing single head recording and reproducing apparatuses is thus provided while offering improved resistance to penetration of dust and other foreign matter into the casing by opening only the aperture(s) required for head insertion.

摘要： A cartridge adaptor accommodates a second cartridge which is smaller than a first cartridge so as to allow the second cartridge to be mounted in a disk apparatus designed to receive the first cartridge. The cartridge adaptor includes a shutter opener engageable with a shutter opener of the disk apparatus to open and close a shutter of the second cartridge, a projection engageable with a recess of the second cartridge to restrict insertion direction of the second cartridge into the disk apparatus, and a conveying member which is inserted into a transmission aperture formed in correspondence with an identification hole formed in the second cartridge, thereby opening and closing a detection hole of the cartridge adaptor formed at a corresponding position to an identification hole of the first cartridge. When the cartridge adaptor accommodating the second cartridge is mounted in the disk apparatus, the shutter of the second cartridge is opened, and the information on a disk housed in the second cartridge provided by the identification hole is correctly detected by the disk apparatus.

摘要： A disc device accommodates a disc rotatably mounted therein, a plurality of first heads movable in a first direction radially of the disc, and a plurality of second heads movable in a second direction radially of the disc and perpendicular to the first direction. The disc has a first surface and a second surface opposite to each other, with an information area defined on at least one of the first and second surfaces. The information area is divided into an outer information region and an inner information region lying radially inwardly of the outer information region. The first heads are allowed to move within a limited distance across the outer information region so as to record or reproduce information on or from the outer information region, while the second heads are allowed to move within a limited distance across the inner information region so as to record or reproduce information on or from the inner information region.

摘要： An optical head which includes a movable bobbin having an objective lens and tracking coils for tracking operation, a carriage guided in such a manner to be able to move in the tracking direction and a state transformation mechanism for transforming the state of the bobbin and carriage between a first state, in which the objective lens can move in the tracking direction but the carriage does not move in the tracking direction, and a second state, in which the movable bobbin and the carriage moves in the tracking direction as one body. When effecting a tracking operation, the state transformation mechanism transforms the state of the bobbin and the carriage into the first state, in which the objective lens can move in the tracking direction but the carriage does not move in the tracking direction, and a tracking drive current is then made to flow through the tracking coils to perform the tracking operation. This results in that the objective lens is supported by a system of a single degree of freedom, of which characteristics are determined by the mass of the movable bobbin and the spring constant of the bobbin supporting means. In contrast, when effecting an access operation, the state transformation mechanism transforms the movable bobbin and the carriage into the second state, in which the bobbin and the carriage move in the tracking direction in one united body, and an access drive current is then made to flow through the tracking coils to effect the access operation. Thereby, tracking performance can be increased and a seeking operation can be performed at a high speed. Further, the tracking coil can be used to effect the access drive operation. Thus, there can be less weight of a movable part of the optical head and lower power consumption.
摘要翻译：一种光头，包括具有物镜的可动线轴和用于跟踪操作的跟踪线圈，以能够沿跟踪方向移动的方式引导的托架和用于将梭芯和托架的状态变换为第一状态，其中物镜可以在跟踪方向上移动，但是托架不沿跟踪方向移动，而第二状态是可动线轴和托架沿跟踪方向作为一体移动的第二状态。当进行跟踪操作时，状态变换机构将筒管和滑架的状态变换为第一状态，其中物镜可沿跟踪方向移动，但滑架不沿跟踪方向移动，并且跟踪驱动然后使电流流过跟踪线圈以执行跟踪操作。这导致物镜由单个自由度的系统支撑，其特性由可动筒管的质量和筒管支撑装置的弹簧常数决定。相反，当进行访问操作时，状态转换机构将可动线轴和滑架转换成线轴和滑架沿着跟踪方向一体移动的第二状态，然后形成存取驱动电流流过跟踪线圈以实现访问操作。因此，可以提高跟踪性能，并且可以高速执行寻道操作。此外，可以使用跟踪线圈来实现访问驱动操作。因此，光头的可移动部分的重量可以更少，并且功耗更低。

摘要： A tray is supported movably relative to a case to enable a second disk to be loaded into and unloaded from a second-disk holding recess. Positioning is performed by using second positioning holes formed through the case and tray. A turntable and a head are inserted through two second opening holes. A second-disk cartridge of thin construction, capable of holding therein the second disk in removable fashion, can be mounted in a recording/reproducing apparatus capable of mounting therein a first-disk cartridge.
