FR2873845A1 - SYSTEM FOR READING AND / OR WRITING ALL OPTICAL MEDIA MULTIPLYING DATA TRANSFER SPEED IN READING AND / OR WRITING, ALSO AVAILABLE TO MULTIPLY STORAGE CAPACITY - Google Patents

Abstract

Optical media reading or read-write system multiplying the speed of read or read-write data transfer. The invention relates to the ROTATION of the read head (s) or of the read / write head (s) The invention reduces the distance between the optical media and the read or read-write head (s), removes vibrations from the optical media (s), removes all the correction devices of current systems linked to vibrations. This invention increases the storage capacity by using optical media formatting and / or pre-formatting adapted to the higher density of the tracks and the lower size of the elementary information unit that the described inventions manage.

Description

The present invention relates to a device for surpassing the

  limitations of the current reading or read-write systems of optical media in terms of information density and speed of information transfer

  $ These limitations are: The limitation of (s) write and / or read speed, related to the information access time and information transfer speed in both directions, the speed of rotation of the optical media in relation to at the reading head (s) or read / write head The current rotation speeds of the optical media are limited because at current speeds (10,000 rpm, in vibration, the optical medium comes into vibration limiting the speed of writing or writing. possible reading / s Limiting information density per square inch Linked to the distance between the read head (s) or the read / write head (s) and the optical and vibration media, this invention applies and improves the results regardless of the technology or technologies used (the use of laser waves plus Zo short and / or multiple useful layers on the optical media) The distance between the optical medium and the (the) read head or ( the read / write head determines the fineness of the unit size of the information on the optical media and therefore the density of the information per square inch, produces the number of tracks per inch multiplied by the number of information on 1 inch of track, so the storage capacity per layer of material on the optical media suppressing vibrations by minimizing in particular the otic aberrations, and eliminating the correction systems of these negative effects.

  Description of a particular embodiment

  An electric motor (A) placed to allow the rotation of a hollow solid cylindrical axis (C) bearing on one of these sides an arm (at least) (G) or a disc containing at least one arm, the length of the Media optical, enclosing in the axis a longitudinal displacement device (on the diameter of the optical media) (I, H, F) of at least one read head or read / write head per arm (J) If the system is equipped with several read heads or read / write head 16, they will be synchronizable or desynchronizable on demand in their movements on each arm in their complementary or additional strokes A zV-shaped aerodynamic drawing envelope for example will contain the (les ) arm and the read head or read / write head that they support the material used will be light, strong, rigid.

  a hollow cylindrical axis will be integral with the engine plate (B), just below we will find for example (this is one of the methods for transmitting the signals of the read head or read / write head to the electronic card of management) a ring (E) which will have in its outer or outer circumference a certain number of circular or electrically isolated S splines / spikes which are electrically isolated from each other will be in contact with the optical media of (the) arms and the ( the read head or reading / writing head rotating to transmit the electrical information (power supplies, signals), to the inside of the ring as many electrical wires as splines / pins will descend via the hollow rigid axis through the electric motor up to the electronic management board (K) This device makes it possible to turn the reading head (s) or read / write head at speeds that are multiples of the current speed and closer to the optical media by reducing the current distances.

  Inserting maintenance of the optical Media, drawer located under the mechanism (D), the optical media is placed on the "useful" surface, and then via a mechanical pusher system, the optical media disk is blocked by the cone of the fixed hollow axis ( B), makes it possible to divide the distance between the reading head (s) or read / write head and the optical media, and to immobilize the optical media. The Applications of this invention may concern the replacement of all magnetic tape systems This device reduces the cost of gigabyte while increasing the volume of data transferred per second also multiplying the storage capacity which will allow miniaturization to equip including: Digital video cameras, PDAs, Digital cameras , Notebooks, USB memory sticks, Printers O Mpeg readers, 2,3,4, Allows replacement of magnetic media, Allows replacement current readers of optical media.
