  • Patent number: 4858036
    Abstract: A method of protecting machine readable signals recorded on magnetic recording media from unauthorized duplication and use. The signals to be protected are recorded on a first portion of the magnetic recording media. The protected signals on the first portion can be detected and altered by the machine. Second signals are recorded on a second portion of the magnetic recording media. The second signals on the second portion can be detected by the machine but cannot be altered by the machine. An attempt is made by the machine to alter the second signals on the second portion. Then, if the second signals cannot be detected on said second portion, the machine is disabled from further using the signals recorded on the recording media. Apparatus for practicing the method is also disclosed.

  • Patent number: 4825321
    Abstract: Higher data storage capacity is realized in a self contained fixed rotating disk expansion board subsystem preferably for a single electronics circuit board accessory slot of a host computer. This greater capacity, e.g. 42 megabytes of formatted storage on two 95 millimeter disks, is achieved by use of a plural zone arrangement wherein each zone contains data tracks in which user blocks are recorded and read out at a data rate unique for the zone. An improved phase locked loop within the data separator uses a separate voltage controlled oscillator for each zone and a commmon charge pump for generating control voltages applied to change the resonant frequency of all of the oscillators, An oscillator disable circuit disables every voltage controlled oscillator other than the selected oscillator, so that it is the only oscillator whose frequency is actually varied by the charge pump during readback/data separation and decode operations.

  • Patent number: 4821126
    Abstract: Based on the fact that the recording track width depends on the width of a core at the trailing side relative to the moving direction of magnetic recording medium, narrower track recording and wider track erasing, or a two-mode recording operation either for high-density recording or normal-density recording are realized using a single magnetic head having a narrower core and a wider core opposing to each other through a gap by changing the moving direction of the magnetic recording medium relative to the magnetic head.

  • Patent number: 4819093
    Abstract: A rotary magnetic recording-reproducing apparatus in an electronic camera system, wherein a subject is purely electronically still-photographed and recorded on a rotating magnetic disc, and the reproduction of an image is carried out by a television set or a printer. When the tracking operation is performed up to the final track and the recording track cannot be detected (an envelope cannot be detected), a warning is issued on the basis of this fact so that loading of an unrecorded disc can be detected. Furthermore, when a track having a number other than one of the numbers of reproducible tracks is to be reproduced, a warning is given so that an operator can be informed of the fact that an unreproducible track has been reached.

  • Patent number: 4816926
    Abstract: This invention relates to an information signal recording apparatus which can be used also as an audio tape recorder only. When it is used only as the audio tape recorder, an audio signal is sampled with a frequency m times the sampling frequency of an audio signal which is used upon recording a video signal and the thus sampled PCM digital audio signal is diffusively recorded on at least two recording intervals thereby to improve the tone quality of the audio signal and the compatibility with the audio tape recorder using a video tape recorder of the same kind can be established.

  • Patent number: 4816938
    Abstract: A process for determining the center of data disk tracks. The transducer head is positioned to one side of a track. The head repeatedly reads the track and microsteps across the track. The number of microsteps taken at the position on each side of the center of the track where a certain number of error correction code errors occur, are designated as boundaries of that track. The center of the track is then calculated as being half-way between the boundaries. By using the microstep off-sets for the centers of two tracks on a data disk, a correction factor can be calculated to compensate for thermal expansion of the data disk.

  • Patent number: 4814905
    Abstract: In a pocket size portable sound recorder, a special pushbutton swith is provided, and pulses are generated according to the number of operations of the pushbutton switch and are applied to a counter as upcount inputs. Also provided is a timer in which a pulse is generated whenever a specified time elapses after depression of the push button switch, and the pulse output is applied to the counter as a downcount input. Since the counter output is applied to the operation control circuit of the recorder, after the pushbutton switch is depressed, the recorder action will be carried out for a predetermined time period until the count value of the counter becomes zero. Also when the counter counts down to a predetermined value a flickering light is generated to indicate that the predetermined time is about to expire. If the special pushbutton is continuously depressed the counter is automatically reset to zero.
