Abstract
The utility model provides an optical disk outer edge positioning type optical disk cassette which is mainly composed of a cassette body and an optical disk positioning card in the cassette body. The optical disk cassette is characterized in that the optical disk positioning card is clamped on the outer edge of an optical disk; thereby, a central hole of the optical disk is retained for facilitating to take. The positioning card not only can be in a fixed structure with certain elasticity, but also can be in a movable structure sliding elastically along the radial direction. In addition, the positioning card is designed into a structure with steps to avoid a real data recording region and a valid reflecting region of the optical disk directly contacting the inner wall surface of the optical disk cassette for preventing data in the optical disk from being damaged by the optical disk cassette.
Description
The utility model relates to a kind of easy unloading CD, the optical disk cartridge little to CD wearing and tearing.
In existing technology and the product, the optical disk cartridge that is used to deposit CD generally all is to utilize the circular hole of cd centre to position and fixing CD.Two kinds of situations appear easily in this structure: the one, cooperate tension, and often will take very big strength could take out CD in box, sometimes even can cause artificial damage to CD; Another situation is to cooperate pine, and CD easily tilts and causes optical disc data recording areas (another side corresponds to effective reflecting surface) directly to contact with the internal face of box in cassette content, easy like this CD is caused wearing and tearing or scratches and influence life-span of CD.China's utility model patent 94207903 proposes a kind of optical disk cartridge structure with unsettled button key, though the unloading CD is more relatively easy, but the structure more complicated, convenience is also also not obvious when going by the press button key with finger in the practical operation, still has the problem of wearing and tearing CD easily simultaneously.
The purpose of this utility model provides a kind of novel optical disk cartridge, unloading CD very easily, and can prevent the wearing and tearing of box to data of optical disk recording areas and effective reflecting surface.
Scheme of the present utility model is as follows: because optical disc data recording areas and effective reflecting surface have no datat (non-usable reflection) zone of 1mm from the outer of CD, so changing the method for normal optical tray salver center pit location is CD edge locator meams: i.e. resilient fixed locator card that around CD, is provided with or the movable locator card that can radial elastic slides, realize the location of CD and fixing; Locator card is designed to the structure of step, thereby makes the contact point of locator card and CD be in the non-data regions and the non-usable reflection district of the edge of CD, thereby can the data in the CD not damaged.
The utility model has been owing to adopted the mode of CD outward flange location, so reserved the center pit of CD so that hold and get.In addition locator card is designed to the structure of step, the inwall of the real data recording areas of the CD of having taken refuge and effective reflecting surface and optical disk cartridge directly contacts, so can avoid optical disk cartridge that the data in the CD are damaged.
Concrete structure of the present utility model is provided by fixed locator card optical disk cartridge embodiment and concrete accompanying drawing.Because the principle of movable locator card optical disk cartridge is identical with it and the locator card slide construction is very easy to realize, does not repeat them here.
Fig. 1 is the fixing principle schematic of CD of locator card.
In the described principle schematic of Fig. 1, the card body (1) of locator card and the step (2) between locator card and the box body contact with CD no datat zone (6) with the non-usable reflection of CD district (3), thereby can not cause wearing and tearing to CD usable reflection district (4) with for data of optical disk posting field (5).
Claims (2)
1. an optical disk cartridge mainly is made of the CD locator card in box body and the box body, it is characterized in that the CD locator card is stuck in the outward flange of CD.
2. optical disk cartridge as claimed in claim 1 is characterized in that the CD locator card has ledge structure.
