Abstract
The utility model relates to an optical disc which can store and reproduce information. The optical disc has the structure that the existing optical disc is carved with storage units which are uniformly distributed and use two concave pits as one set, wherein, mediums inside two concave pits in each unit are connected with each other by a slit and covered by a cover board which has homogeneous light penetrating property. The storage units of the novel optical disc can be composed of mutually transferred mediums, so that the utility model can conveniently store information, and solve the problem that the existing optical discs only can read but can not store information.
Description
The utility model relates to CD.
At present the CD that uses of people can only read information, and canned data is very inconvenient, can not change the content of being stored, and user individual can not this process of operation store information, and this just brings great inconvenience to the user, and addressing this problem becomes urgent need.
Task of the present utility model is: overcome the deficiencies in the prior art, design and a kind ofly can store the CD of the information of reading repeatedly.
Task of the present utility model realizes as follows: carve two uniform little holes and be one group storage unit on existing CD, the medium in two pits each unit in is continuous by a slit, and topped by the uniform cover plate of printing opacity.
The utility model constitutes storage unit owing to CD is provided with by the medium that can shift mutually, so easily canned data.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the sectional view of Fig. 1.
A most preferred embodiment of the present utility model, as figure, two nick holes that carve regular distribution on CD 3 are one group storage unit 1,2, pit in each unit is linked to each other by a slit, medium in the pit is realized shifting mutually by slit, medium in little hole of scribing on the CD and the slit is topped by the uniform overcoat of a printing opacity, to guarantee that storage medium can only shift in the unit.
Its course of work is:
The zone of this CD is identical with showing general optic disc with track, to reach read-write machine energy compatibility, to read dish.The utility model key of canned data repeatedly is storage unit and the method that each medium that can shift mutually constitutes.Input flows to medium 2 for medium 1 by laser beam with prime information is topped during fresh information, represent a binary number 0, otherwise 1 is not considered as representing a binary number 1 much smaller than 2, during read message, only open away laser beam 1 at front end, this machine light device is used for sense information, and power is little, does not make the medium circulation.During canned data, still be in read states corresponding to the laser instrument 1 of medium 2, examine then that a is 0 or is 1, if need not change, the laser instrument 2 of then corresponding medium 1 is closed, and changes if desired then that laser instrument 2 (rearmounted laser instrument) sends a highpowerpulse, makes the medium circulation.Example: need storage unit a is whether be 1 to 1, the first laser beam if having detected a when shining the medium 2 of a.If a is 0, then when laser 1 shone the medium 1 of next storage unit b, laser 2 was over against the medium 2 of answering a unit, and 2 one high power pulses of laser this moment make 2 to flow to 1, and then a unit becomes expression 1; If a is 1 then does not revise.Needing a is 0 o'clock, and whether first laser beam has detected a when shining a unit medium 2 be 0, if be 0 then do not revise, if be 1, this moment laser beam 2 over against the medium 1 of answering a unit, and send a high power pulse, make medium 1 flow to 2, a represents 0.Medium 1,2 circulation mutually is to realize that by the slit that connects them distance of each unit equates under laser action.And the little hole and the slit that are installed in medium are also identical respectively, read and write this optical disc apparatus and comprise the relatively microprocessor formed of detecting device and controller, and to be used for relatively detecting each memory cell be 0 or be 1, and send the instruction of whether revising.
Claims (2)
1, a kind of storage and the CD of information reproduction, it comprises an optical disk carrier, it is characterized in that: be carved with two uniform little holes on the CD and be one group storage unit, the medium in two pits in each unit is linked to each other by a slit, and topped by the uniform cover plate of printing opacity.
2, CD as claimed in claim 1 is characterized in that: the slot distances of two pits of connection of said each unit is identical.
