  • Patent number: 6654540
    Abstract: The disclosure relates to a recording and reading apparatus constituting a kind of video reservoir in the home of the consumer. Thanks to a large-capacity storing technique with suitable technical means, broadcasters transmit numerous programs via specific channels and the consumer may control the content of his reservoir (by recording, reading and erasing programs). The invention is applicable to on-demand video in the consumer's home with a video reservoir constituting a video-library that is regularly updated by broadcasters and/or by the consumer himself.

  • Patent number: 6629196
    Abstract: The invention relates to a method and device for obtaining an adaptive selection of sets of data stored in a mass memory. The method and device use administrative information stored in a administration memory and related to the data sets, and allow to obtain a classified list of data sets. The adaptive selection may reflect habits of access to the sets of data by a user as well as momentary preferences of the user.

  • Publication number: 20030051095
    Abstract: The invention relates to a method and a device for obtaining an adaptive selection of sets of data stored in a mass memory (30). The method and the device use administrative information stored in an administration memory (31) and related to the data sets, and allow to obtain a classified list of data sets. The adaptive selection may reflect habits of access to the sets of data by a user (35) as well as momentary preferences of this user. The data sets may for example be songs recorded on a magnetic tape (29).

  • Patent number: 6470411
    Abstract: The invention relates to a method of access to data sets stored in a bulk memory. During an access time to a data set, the method provides for reading introduction data and exploiting these. This way the method overcomes the problem of long access times in a bulk memory. The method may notably be used when data sets are arranged sequentially on a sequential data carrier, which is for example the case for songs recorded on a magnetic tape. A device for implementing the method is also defined.

  • Patent number: 5889920
    Abstract: A receiver/recorder for television transmissions whereby continuous recording of television transmission occurs from at least one channel onto a random-access rewritable recording medium. At each of a plurality of predetermined locations a binary code is periodically written to represent a filling of predetermined portions corresponding respectively to the predetermined locations. An indexing device responds to the binary code in order to automatically distinguish between a first in time recorded transmission on the medium from a second in time recorded transmission on the medium at a particular one of the predetermined locations.

  • Patent number: 5659536
    Abstract: Disclosed is a system for the recording of data on optic disks. Presently used optic disks, which can be read with lasers working in wavelengths of the visible region (between 0.5 and 0.8 microns), have a maximum surface storage density of the order of one data bit per elementary zone having an area of about one square micrometer. Beyond this limit, the diffraction does not allow the neighboring zones to be distinguished. A means is proposed to considerably increase the storage capacities: in an elementary zone of a layer, an information bit is written not in the form of a point of absorption of a laser light but in the form of a diffraction grating with a determined pitch. Several diffraction gratings, having pitches different from one another, may be superimposed at the same position, enabling the recording, in one and the same zone, of several information bits. The diffraction gratings are made by a periodic local variation of the optic index of the layer.

  • Patent number: 5067230
    Abstract: A method of simultaneous manufacture of a plurality of planar magnetic heads on a wafer or a slab made of non-magnetic material designed to be cut out to separate each head. The method can be applied to magnetic heads of the type including a micro-gap formed between two magnetic poles, facing a gap defined between two wire-wound ferrite cores. The method consists in depositing said thin layer magnetic poles on a first face of a wafer made of non-magnetic material and in hollowing out, in the face opposite to said wafer, at least one cavity for housing said wire-wound cores so as to obtain a calibrated spacing or a junction between the upper part of each of said wire-wound cores and said thin layer magnetic poles.

  • Patent number: 4939836
    Abstract: A method for fabricating magnetic recording/reading heads. A substrate made of magnetic material is provided with a groove of a predetermined width. The surface of the substrate bearing the groove becomes the active face for the magnetic head. The face of the substrate having the groove is ground, and then filled with a non-magnetic material to form a gap. The filling causes the non-magnetic material to jut out of the groove. The material which juts out is ground off until the level of the substance is reached.

  • Patent number: 4939835
    Abstract: A method for achieving the planar surface of an active face for magnetic recording/reading heads. The planar surface of the active face is obtained by grinding, the active face being of the type where, before the grinding operation, the level of the material forming the gap is recessed with respect to the magnetic poles, the method comprising depositing over the recess a thin layer of non-magnetic material with a thickness at least equal to the recess of the gap. The non-magnetive thin layer may then be ground to obtain the planar surface of the active face.
