    • A method and system of placing information on a photosensitive film having a magnetic layer provides for the storage of image data on the magnetic layer of the film in a manner which permits the image data to be easily recalled and displayed on a monitor. The system and method can utilize an enabled Advance Photo System camera which is capable of reading digital data magnetically encoded on film. The information can be compressed and written onto the film at the time of film processing. The enabled Advanced Photo System camera reads this information and is connectable to a host computer for permitting the transfer of the information from the camera to the computer. At the computer, the digital image data can be decompressed and viewed by a user for downstream manipulation of the images.
    • 将信息放置在具有磁性层的感光膜上的方法和系统提供了以允许图像数据容易地被回忆并显示在监视器上的方式将图像数据存储在胶片的磁性层上。 该系统和方法可以利用能够读取在胶片上磁编码的数字数据的启用的高级照相系统摄像机。 在胶片处理时,可以将信息压缩并写入胶片上。 启用的高级照片系统摄像机读取此信息,并且可连接到主机,以允许将信息从摄像机传输到计算机。 在计算机中,数字图像数据可以被用户解压缩并被观看以用于图像的下游操纵。

    • When a rotary-actuator voice coil type disk drive is powered down the actuator arm is moved to a parking position against an I.D. stop by a disk spindle motor back EMF, resulting from the spinning down of the spindle motor. Current is applied by the back EMF through a delay circuit to a latch arm voice coil on one end of a latch arm and forming part of a magnetic circuit including a drive permanent magnet on a ferrous base plate and a ferrous upper plate. Resultant movement of the latch arm overcomes a spring bias of a torsion spring extending between the base plate and pivoted latch arm normally keeping the latch arm in an unlatched position. A latch permanent magnet extends from the other end of the latch arm and is brought into spaced proximity, but not contact, with a ferrous member extending from the actuator arm so that the magnetic force therebetween holds the actuator arm against the I.D. stop in latched position to withstand high shock loadings. Powering the rotary actuator voice coil motor up overcomes the magnetic force and allows the biased torsion spring to move the latch arm to the unlatched position without resultant loss of data storage area.
    • 当旋转致动器音圈型磁盘驱动器断电时,致动器臂被移动到与I.D.相对的停车位置。 由主轴电机反转的磁盘主轴电机停止,由主轴电机的下降引起。 反电动势通过延迟电路将电流施加到锁臂的一端上的锁臂音圈,并在铁基板和铁上板上形成包括驱动永久磁铁的磁路的一部分。 闩锁臂的产生的运动克服了在基板和枢转的闩锁臂之间延伸的扭转弹簧的弹簧偏压,通常将闩锁臂保持在解锁位置。 闩锁永磁体从闩锁臂的另一端延伸并且与从致动器臂延伸的铁构件隔开接近但不接触,使得其间的磁力将致动器臂保持抵靠于I.D. 停止在锁定位置以承受高冲击载荷。 向旋转执行器音圈电机供电克服了磁力,并允许偏置的扭转弹簧将闩锁臂移动到解锁位置,而不会导致数据存储区域的损失。

    • The camera of the invention includes a magnetic recording head adjacent the film and a processor which senses the lens focal length, the aperture size, the shutter speed and the film ISO number or film speed, and makes the following determinations: First, it determines from the scene brightness and film speed whether the ideal combination of shutter speed and aperture size, in terms of a required exposure value, falls within the range of maximum and minimum shutter exposure times and aperture sizes of which the camera is capable of providing, expressed in terms of a minimum camera exposure value and a maximum camera exposure value. If the ideal exposure value for that scene falls outside the range of camera exposure values, then the processor causes a magnetic recording head to magnetically record in or adjacent the current film frame a coded indication symbolic of the fact that the required exposure value was beyond the camera exposure value range.
