Abstract: A control system for fully automatic turntables is revealed. The control system includes a receiver module therein for receiving signals from application programs to activate a drive source and a control assembly which control a platter and a tonearm respectively. The control assembly includes a first rod provided with an upper rack and a second rod provided with a lower rack. The first and second rods are inserted and installed on a base. A power source disposed on the base is for driving a first gear set correspondingly and a connecting rod is also moved to drive a second gear set. Thus partial gears of the first and second gear sets are engaged with the upper and lower racks alternately. The first and second rods are further driven to move or stop the tonearm respectively. Therefore, automatic movement of the tonearm is achieved.

Abstract: An information recording apparatus has a stop mode in which only recording means comprised of a rotatable drum on which a recording head is mounted and recording medium driving means comprised of a capstan/pinch roller are stopped, which stop mode can be changed from a record temporary stop mode. During the stop mode of the recording means and the recording medium driving means, a video signal photo-taken by a camera of the information recording apparatus can be outputted externally, and, change to the stop mode is made effective by a combination of user's selection and/or presence/absence of an external connection device.

Abstract: The present invention relates to a method for ejecting a disk completely even though it has been caught in a slot while being ejected with its upside down or because of malfunction of a sensor detecting whether a disk has been ejected or inserted. This disk ejecting method drives a disk ejecting motor for a predetermined time irrespective of the output status of a sensor detecting whether a disk has been ejected, when a command requesting ejection of an inserted disk is received.

Abstract: A disk texturing tool is used, for example, to provide textured spots in an annular portion of both sides of a disk for a hard disk drive. Disks are moved into and out of the texturing process in cassettes, through two disk-handling stations. An optical system includes a laser directed at a beamsplitter to split the laser beam into two beams having approximately power, which are directed along parallel paths through a power control optics block to expose simultaneously opposite sides of a disk to be textured. The power level of each of these two beams is controlled by a program which operates in a teach mode to develop a look up table describing laser beam power as a function of a signal driving an attenuator, in a set point mode setting this drive signal to provide a certain laser beam power, in a run mode controlling this power through a feedback loop, and in a display mode showing laser beam power as a function of time.

Abstract: An apparatus and method is provided for detecting and sorting a document containing an address change request from a group of documents. The apparatus includes a document transport for conveying the document along a selected path of movement. An image scanner positioned along the selected path is provided for reading an image of the document or of a selected area on the document. The image scanner provides density levels corresponding to discrete areas on the document. An image processor determines a set of density levels corresponding to a test line passing through the selected area on the document. Density level transitions are detected along the selected line when two adjacent areas on the document have substantially different density levels. If a sufficient number of density level transitions are detected along the selected line, the document is sorted from the group of documents.

Abstract: A molecular memory medium for storing digital bits at a density of several hundred million per square centimeter. The medium is read and written by a tunnelling probe, and comprises a plane surface and a means for moving the surface relative to the tunnelling probe. Arrayed on the surface are plural memory elements, each storing one bit, and having, relative to the surface, a first positional state and a second positional state, representing the first state and the second state, respectively, of the bit. The positional states are distinguished from one another by a difference in a tunnelling current in the tunnelling probe. The memory element is switched from one positional state to the other by an electrostatic force applied by the tunnelling probe.

Abstract: A record player having a mechanism for guiding and centering records of different sizes on a driving spindle. Two pairs of levers are mounted on a record carrier at diametrically opposed positions. The levers have generally circular hubs mounted on pivots carried by the record support and extending arms including record engaging studs. Insertion of a record engages the studs to pivot the arms which guide the record to a centered position. Alignment of slots in the hubs of at least one of the pairs of levers sense the proper positioning of the record and trigger the player to rotate the record carrier from the load to the play position.
