Abstract: A tone arm assembly for record players having a first motor for rotating a tone arm in the vertical direction, a second motor for rotating the tone arm in the horizontal direction with respect to a record disc, respectively, a detector for detecting low frequency vertical and horizontal vibrations of the tone arm during the reproduction of a record disc and feeding back an output sign 1 of the detector to the motors so as to cancel the vibrations, whereby high fidelity reproduction of sounds can be performed. Further, the stylus pressure adjustment and elevation angle adjustment of the tone arm are also performed.

Abstract: A phonograph record turntable assembly comprises a rotatable turntable having a rubber or other elastically flexible sheet overlying a substantial portion of its upper surface and secured thereto at least along an edge or edges of the sheet for defining at least one sealed interior space which contains a fluid material, preferably in the form of a viscous liquid, so as to provide a cushioned, vibration-damping record supporting surface which conforms to the shape of a warped or otherwise distorted phonograph record placed thereon. In order to avoid the accumulation of the liquid at any one portion of the interior space when the turntable is not horizontally disposed, such interior space may be divided into a plurality of liquid-containing compartments which are isolated from each other, as by partitions therebetween, and/or each interior space or compartment may further contain absorbent material which takes up the viscous liquid. The vibration-damping properties of the turntable assembly may be enhanced by providing solid particles which float in the viscous liquid.

Abstract: A data recording apparatus is capable of easily preventing copying of information in that, even if information is copied, the copied information cannot be reproduced. The data recording apparatus has a terminal (2) to which encoder identification information ("ID") specific to the data recording apparatus is input, a recording unit (5) for recording at least the encoder ID on an optical disk (D), and an encoding circuit (3) for encoding, in accordance with the encoder ID, data supplied via a terminal (1) and required to be recorded so that encoded data is, together with the encoder ID, recorded on the optical disk (D).

Abstract: An input is ciphered in at least one of a sector forming circuit 13, a scrambling circuit 14, a header appendage circuit 15, an error correction encoding circuit 16, a modulation circuit 18 and a synchronization appendage circuit 18, used for processing input data for forming a recording signal. Not only the key for ciphering itself in the circuits but also the information as to which of the circuits has been used for ciphering becomes the key for ciphering. This realizes ciphering difficult to decode by a simplified structure.
