    • The invention relates to a suspension arm actuator comprising a suspension arm which is designed as a two-arm lever and is mounted between the lever arms such that it can be pivoted about an axis extending perpendicularly thereto. At its end side, one of the lever arms supports a sensor, in particular a scanning device comprising an optical head having a focal lens, and comprises an elastically bendable region formed of at least one leaf spring and intended for a motion of the optical head in focusing direction and perpendicularly to the pivot plane of the suspension arm. In order to initiate said motion, a magnetic drive is allocated to said lever arm. The other one of the lever arms is provided with a component of a magnetic drive for a swivel motion about the axis. It solves the problem of designing such a suspension arm such that the free end of the lever arm supporting the optical head has a lower tendency towards mechanical resonances, associated with a reduced en- ergy consumption. To achieve this, the at least one leaf spring (4) which extends in longitudinal direction in relation to the suspension arm (1) and is arranged in parallel to the pivot plane thereof is embedded in the sections (I.1 and I.2) of the lever arm (I) supporting the optical head (3), said sections (I.1 and I.2) delimiting the bendable region (5), wherein said leaf spring (4) is enclosed by a damping means (DM) at least in one partial region arranged adjacent to each of said sections (I.1 or I.2).

    • An optical assembly includes a service loop extended from a focus section of an actuator arm. A portion of the service loop bends when a tracking section of the actuator arm rotates around a tracking axis while a portion of the flex circuit twists when the focus section of the actuator arm rotates around a focus axis. A method is provided to predict the shape of a service loop that will not rotate the actuator arm from a resting position. The method uses a number of deflected beam elements to simulate the service loop under simple beam theory. In order for the actuator arm to remain in the resting position, the method assumes that the service loop applies an equivalent force to the actuator arm through the rotation axis of the actuator arm. Another method is provided to calculate the restoring torque exerted by the service loop when the actuator arm is rotated from its resting position. The method again uses deflected beam elements to simulate the service loop but assumes that the service loop applies a force that is offset from the rotation axis of the actuator arm.
    • 一种光学装置包括从致动臂的聚焦单元延伸的服​​务环路。 当致动臂的跟踪单元围绕跟踪轴旋转时,部分服务环弯曲。 同时,当致动臂的聚焦单元围绕聚焦轴旋转时,柔性电路的一部分扭曲。 本发明还涉及一种用于提供不会使致动臂从静止位置旋转的服务回路的形状的方法。 该方法使用多个偏离的梁单元根据简单梁理论来模拟服务回路。 为了将致动臂保持在静止位置,所述方法的特征在于,服务回路在致动臂的整个旋转轴线上施加相等的力。 此外,本发明涉及另一种用于在致动臂从其静止位置旋转时计算由检修回路施加的反向扭矩的另一种方法。 该方法还使用偏转的梁元件来模拟服务回路,这次施加偏离驱动臂旋转轴线的力。

    • An information processing apparatus is preferably made to contain hardware components of plural turntables, plural head units, plural decoding units, at least one encoding unit, and a system control unit. These components are adapted in such a manner as to afford (1) true multitasking in information reading and writing, (2) direct communication for information to be exchanged directly within the information processing apparatus, (3) disc removability for information to be stored as off-line archives and to become transportable between computer systems, (4) separation of user-created data from program files for eliminating time-consuming file-defragmentation processing and for conveniently safekeeping the user-created data, and (5) capability of launching favored software programs direclty from original software discs. In essence, the apparatus provides multiple and highly-improved functions of secondary and tertiary storage that cannot be obtained from any combinations of conventional hard-disk, floppy-disk, optical-disc, and backup drives.
