Description
本申请是申请日为1997年1月14日,申请号为97191783.3,标题为“直接施加于光记录媒体的电子物品监视标记”的专利申请的分案申请。
技术领域
本发明涉及专门的标记,这种标记在磁型电子物品监视(EAS)系统中是有用的,它可以直接施加于光记录媒体的表面,而不对媒体的工作和耐久性有负面影响。本发明的标记包括单态标记和可逆可再激活双态标记,它们在磁型电子物品监视(EAS)系统中都是有用的。
背景技术
磁型EAS系统广泛地应用于抑制对商品(诸如服装、书籍、盒式磁带和光盘)的偷窃行为。电子物品监视(EAS)系统常常用于防止未经许可地将物品从一保护区域(诸如图书馆或零售商店)中移走。EAS系统常常包括位于保护区域的出口附近的询问区或者过道及附在要被保护物品上的标记或者标签。EAS系统曾基于磁性、RF、微波及磁性限制(magneto-restrictive)技术。不管所包含的特殊技术如何,EAS系统如此地设计,从而当暴露于过道中的询问信号时,标签将产生某些特征响应。对这种特征响应的检查指出在过道中有激活标签。然后EAS系统实行一些适当的安全措施,诸如发出听得见的警报音、锁住出口等等。为了允许从保护区域经许可地移走物品,常常使用永久去激活标签或者可逆去激活标签(即,双态标签)。
虽然EAS标记已经普遍用于光记录媒体(诸如小型光盘和CD-ROM)的防窃,但标记通常适合于附于装有新的小型光盘的包装上,而不适合于直接附于小型光盘本身。对于图书馆和其它要应消费者和客户的要求反复收回和借出的小型光盘的机构,最好用有效的存货控制,即把EAS标记附于小型光盘上。
已经开发了一些用于直接附于小型光盘上的标记。一种是附于小型光盘的单态标记条和防护覆盖物的可从Minnesota Mining and Manufacturing Company,St.Paul,MN购得的“DCD-1”。但是,这种标记对盘片的机械平衡起负面影响,这会给现代高转速的CD-ROM驱动装置、CD唱机及其它光记录媒体播放设备的工作带来负面影响,它们需要媒体机械平衡,以适当地工作。可从Knogo North America,Inc.,Hauppauge,Long Island,NY购得的另一种产品“CD-Guard”遇到同样的机械平衡的缺点。在共同转让的第5,347,508号美国专利中描述了一种光信息存储光盘,这种光盘包括嵌入的,通常为环形的双态EAS标记。
因此,现有技术中需要一种为保护光记录媒体而特别设计的标记。
发明内容
本发明是一种适合直接施加于诸如小型光盘、CD-ROM、激光视盘(LD)和数码视盘(DVD)之类的光记录媒体上的电子元件物品监视(EAS)标记。这种标记包括一支持层和一个或者更多的标记元件,这些元件如此地放置,从而标记的质量分布关于标记的中心对称地设置。当标记适当地位于光记录媒体上时,这样做保证标记对媒体的机械平衡不产生负面影响。
附图说明
当阅读和理解下面的详细的描述即附图时,本发明的各种目的、特征和优点将被更好地理解,这些附图是:
图1示出根据本发明的标记的一个实施例;
图2A和2B示出图1所示的类型的标记的侧视图;
图3示出双态标记元件的简化侧视图;
图4A和4B示出附于小型光盘上的本发明的标记的两个实施例的侧视图;
图5A和5B示出交替双向响应双态标记的俯视图;
图6A和6B示出为强制标记元件到小型光盘的非记录区域而设计的交替标记的俯视图;
图7、8、9和10示出用于生产本发明的标记的过程。
具体实施方式
在下面的详细描述中,参照了附图(它构成了说明书的一部分),并通过描述一实践本发明的具体的实施例的方式示出。应该知道,在不背离本发明的主旨和范围的情况下可利用其它的实施例,并且可有结构上的变化。
本发明是一种适合直接施加于诸如小型光盘、CD-ROM、激光视盘和数码视盘影之类的光记录媒体的电子物品监视(EAS)标记。为了描述的简便,下面的详细描述将常指小型光盘的特殊情况;但是,熟悉本领域的人将容易地认识到这里描述的标记适用于任何光记录媒体。
作这种应用的EAS标记容易施加至光记录媒体的暴露的表面,提供良好的检测性能,不妨碍媒体或者读取媒体的设备的实际操作,并且不对媒体引起短期或者长期的损伤。具体地说,标记上的粘合剂必须对用于媒体中的任何材料化学上不起反应,而且标记的安装必须对媒体的机械平衡不产生面影响。还有,标记最好应和检测特性以及在一般的EAS系统使用中激活/去激活设备相容。
用于光记录媒体电子物品监视(EAS)标记10的第一实施例的俯视图示于图1中,而其侧视图示于图2中。标记包括圆形支承片12,该支承片具有居中的同心圆孔14,及两个标记元件16和18,它们如此的放置从而标记10的质量分布关于标记10的中心对称地设置。这保证了当标记10适当地置于小型光盘上时,标记不对光盘的机械平衡产生负面影响。光盘的机械平衡对高速CD-ROM驱动装置、CD唱机和其它光记录媒体播放设备的合适操作是非常重要的。标记10还包括用于将标记附于小型光盘的粘合剂层24(图2A)。
支承片12的孔14对准机构的作用,帮助用户适当地将标记放置在小型光盘或者其它光记录媒体上。孔14在支承片12上居中,而且其尺寸和形状大致上相应于典型的CD、CD-ROM、激光视盘或者其它光记录媒体中的孔。最好通过提供具有相应于媒体的实际尺寸的不同尺寸的支承片及居中的孔来使标记适合不同的媒体。为了将标记10附于小型光盘上,用户只需用媒体的孔对孔14定位。当两个孔对准时,标记可附于媒体上。通过适当地将标记放置在媒体上,标记的机械平衡确保媒体上具有的标记不对媒体或者任何媒体播放设备(诸如CD唱机或者CD-ROM驱动装置)的性能产生负面影响。
在图2B所示的另一个实施例中,标记11还包括在粘合剂层24顶部的分离衬垫(release liner)23。分离衬垫保护粘合剂层24不受损伤及和其它表面的意外附着。为了将标记11附于小型光盘上,去掉分离衬垫,露出粘合剂层24,然后把它用于将标记附于小型光盘上。
标记元件16和18可以是双态或者单态的元件。如果标记元件16和18是单态的,则标记元件16和18可以由低矫顽力、高磁导率的磁性材料的信号产生层构成。对于双态标记,图3中示出几种可能的实施例中的一种。图3示出在共同转让的第3,765,997号美国专利(它通过引用包括于此)中描述的类型的双态标记元件的侧视图。双态标记18包括低矫顽力、高磁导率材料的信号生产层32和信号阻挡层34,该信号阻挡层包括多个可剩余磁化的磁性材料的部分36。在另外的实施例中,信号阻挡层34可以是可剩余磁化的磁性材料的相连的层。
再参照图1,标记元件16和18最好是平行排列,并且对称地设置在孔14的相对侧。在一个较佳实施例中,更好地放置标记元件16和18,使它们的内边相隔大于4cm的距离并且更好地选出标记元件18和20的尺寸,从而它们从孔14的中心算起的最大的径向长度小于大约5.9cm。
图4A示出附于小型光盘28的表面的标记10的侧视图。支承片12、标记元件18和粘合剂层24用粘合剂层24附于小型光盘28的第一侧26。较好地,第一侧26是小型光盘28的非记录或者“标签”侧,而小型光盘28的第二侧30是可光检测的记录表面30。在这个实施例中,支承片12最好设计得保持附于小型光盘28,并用作保护标记元件16和18不受损伤和淬硬。
在图4B所示的另一个实施例中,支承片12如此地设计,从而它是可分离的。在这个实施例中,用于将标记元件附于小型光盘的粘合剂24应比用于将标记元件附于支承片的粘合剂(图中未示)更有粘性(aggressive)。按照这种方法,一旦标记元件附于小型光盘28上,就把支承片12去掉,使标记元件16和18附于小型光盘的表面上。这个实施例对于某些应用较佳,这些应用不希望有支承片(如果让它附于小型光盘)的附加重量。
对于诸如图4A中所示的小型光盘的应用,支承片12最好是无色透明的,允许容易地读出印在小型光盘28的表面26上的信息,同时提供对标记元件和标签的保护。为了选出的小型光盘应用,最好至少支承片12的一些部分包含白色颜料和/或具有可印刷的表面,从而支承片可以作为标签。
除了图2A-B和4A-B所示的实施例(其中标记是由支承片12、标记元件16和18及粘合剂层24构成的元件叠层),应当理解,改变元件的叠层顺序其它实施例也在本发明的范围中。例如,元件的顺序可以是支承片12、粘合剂层24和在粘合剂层24的顶部的标记元件16和18,这不背离本发明的范围。
在和任何用于构造光记录媒体或者其标签的材料的相互作用方面,适合用作粘合剂层24的粘合剂材料最好有化学惰性。换句话说,粘合剂24最好对任何用于构造媒体或者其标签的材料是不起反应的。另外,用于粘合剂层24中的材料不会从层中漏出或者移动,从而和驱动机构或者播放设备、存储器等等的其它内部部件接触,或者腐蚀媒体上的反射涂层等等。一种较好的粘合剂可以从Minnesota Mining and Manufacturing Company,St.Paul,MN买到它是No.9461PTransfer Adhesive。
在标记10的一个例示实施例中,支承片12是透明的涤纶树脂薄膜的圆形部分,厚度为50微米(2mils),直径为11.4cm(4.5in.)。中心孔14直径为1.7cm(0.67in.)。标记元件18为大约7.7cm(3in.)长和1mm(40mils)宽。与标记元件18共同延伸的信号产生层32为大约18微米(0.7mils)厚,并由一种非晶磁性合金(由大约67%(原子百分比)Co、5%Fe和25%B和Si组成)制成,这种非晶磁性合金可从Allied Signal Corp.,Parsippany,New Jersey买到,产品号为2705M。信号阻挡层34包括多个分隔部分,每个部分大约5mm长,40微米厚,以及和信号产生层相同的宽度,由FeCr合金制成,这种合金可以从ArnoldEngineering of Aarengo,Illinois买到,名为Arnokrome 3。在这个较佳实施例中,用于例示标记中的Arnokrome 3的样品要受到退火处理,以达到大约为200+/-30奥的均匀的矫顽力。还是在这个较佳实施例中,产品号为2705M的样品被退火,以降低矫顽力,并增加横穿薄片(cross-web)方向的各向异性。虽然这里描述,具体的材料,但熟悉本领域的人应该知道,可使用不同的材料和不同的标记结构而不背离本发明的范围。
在一个实施例中,当处于激励状态由EAS系统询问时,标记元件16和18最好在尺寸、材料的规格及其产生的特征信号方面大致相同。在另一实施例中,标记元件在尺寸、材料规格方面不同或两者都不相同,以产生一个组合特征信号,这个特征信号可检测地不同于各个标记元件的特征信号,环境噪声信号源等等。
图5A中示出本发明的双态电子物品监视(EAS)标记60的另一种形式。标记60类似于共同转让的第4,829,288号美国专利中描述的标记,该专利通过引用包括于此。标记60包括圆形支承片62,该支承片具有一个居中的同心的圆形孔64,还包括四个狭长的矩形的标记元件66、68、70和72。标记元件66、68、70和72最好关于孔64的中心对称地设置,并且在一个较佳实施例中,元件66、68、70和72的内边形成一个正方形。在一个特殊的实施例中,元件66、68、70和72被如此地放置,从而它们与标记的中心相隔的最近的距离最好是至少1.9cm。标记元件66、68、70和72的长度和宽度尺寸如此地选择,从而它们从孔64的中心算起长度最好小于大约5.9cm。分立的标记元件66、68、70和72,起着正交的开关元件的作用,使标记60具有“双向”响应。虽然在图5A中描述了一个实施例中的标记元件66、68、70和72,其中各个元件的端部相互实际上分开,但熟悉本领域的人将容易地认识到,标记元件相邻端部互相接触也在本发明的范围之内。还有,具有奇数个非正交排列标记元件的EAS标记(例如具有按等边三角形布置的标记元件的EAS标记(未示出)也在本发明的范围之内。再者,一个重要的特点是,标记的质量对称地关于标记的中心设置,因此,保证了在标记被附着之后保持小型光盘的机械平衡。
图5B中示出“双向响应”双态标记的另一种形式。标记76类似于第4,746,908,4,825,197和4,967,185号美国专利中所述的标记,这两项专利通过引用包括于此。标记76包括圆形支承片12,单个标记元件80包括邻接的信号产生层,这个信号产生层绕支承片12的中心孔14延伸。标记76具有隅角部分84、86、88和90,它们用作磁通量的收集器,以集中来自询问区域通过相互连接部件92、94、96和98的磁通量,这些隅角部分起着检测开关元件的作用。
上述实施例对只在一个表面上可记录或者已记录的小型光盘是有用的。对于两面都可记录的小型光盘或者激光视盘,或者对于想要对单侧小型光盘的记录侧作标记的应用,最好采用诸如图6A和6B中所示的标记。图6A的标记包括在支承片12上的两个标记元件17和19,它具有居中的,同心圆孔14。图6B的标记40包括图5B中所示类型的单个标记元件41。在图6A和6B中以虚线13示出的环相应于光记录的不记录区域或者“中心”区域。该不记录区域13是CD-ROM驱动装置或者CD唱机夹在小型光盘上的部分。对大多数小型光盘,不记录区域半径为大约1.9cm,虽然应知道,对于这个实施例,标记元件只需在光记录媒体的中心区域内,而不管其特殊的尺寸如何。
在图6A和6B所示的实施例中,标记元件17、19和41分别位于标记20和40上,从而标记元件附于小型光盘的不记录区域。通过将标记元件限制在小型光盘的不记录区域,标记元件无法干扰CD-ROM驱动装置或者CD唱机的光盘读出机构。另外,标记元件再次小心地被放置,以保持被它们所附的小型光盘的机械平衡。
图7-10中示出生产图1所示的类型的双态标记10的过程。首先通过将可剩余磁化的箔带110与高导磁的磁性箔带102适当地对准接触,并将带104涂有粘合剂一侧,与露出的箔102和箔110的表面层叠(通过在压紧滚筒112和114之间在压力下以接触方式传送它们),产生图8的侧视图中所示的EAS标记结构100的连续的卷。
图9示出这个过程的下一个阶段,该阶段中,标记结构100被放入剪切工位120,它剪下一条窄带以形成标记元件16(切下的长度尺寸等于标记结构100的宽度),并将标记元件16可分离地粘附到临时带送116的低粘性粘合剂侧118。在一个较佳实施例中,在临时传送带116的粘合剂侧118上覆盖了压敏粘合剂。一种例示性的传送带是No.295带,它可从Minnesota Mining and ManufacturingCompany,St.Paul,MN买到。但是,也可以使用其它合适的压敏粘合剂传送带。
在工位120中,导轨和定位装置沿和传送带116传送的方向正交的方向传送标记结构100的大致上连续的带,从而如此形成的标记元件16固有地排列以(其长度尺寸沿传送带116的长度尺寸)。用于两条正交带的导轨和定位装置被如此地放置,从而当施加给传送带116时,标记元件将粘附在偏心位置。通过在每个标记元件16被剪切并施加给其低粘性的表面后,使传送带116的位置递增推进而沿传送带116的长度依次地施加一系列偏心标记元件16。
在第一实施例中,通过在施加标记元件16后将传送带旋转180°把其它的标记元件18加至传送带116低粘性的粘合剂表面118的上与标记元件16相对的偏心位置,并通过剪切工位120再次传送传送带116。在在施加了标记元件116后传送带116重绕到其供带轴上的过程中,传送带116必须沿相反的方向通过剪切工位120,以使标记元件18有适当的偏心位置。在另一种过程改变中,有标记元件16附于粘合剂表面18的传送带116临时地留在卷带轴上,并且把卷带轴取下并安装到原来供带轴的位置。然后把传送带116沿用于安装标记元件16的相同的方向通过剪切工位120,以达到标记元件18的偏心定位和附着。在任一个过程中,必须控制传送带116的纵向定位,从而标记元件16将处于和标记元件18相同的纵向位置。这保证了保持标记元件在标记上的适当的位置,以保证当标记被适当地附着于小型光盘时它有适当的机械平衡。
在另一种过程的改变中,如图10所示,使传送带116依次通过施加标记元件16的剪切工位120,和在反向的偏心位置施加标记元件18的第二剪切工位120’。剪切工位120和120’的之间的间隔如此地设置,从而标记元件16和18对准,以得到适当的平衡的标记。图10示出标记结构100,从那里剪切标记元件16,移入剪切工位120,及标记结构100’,从那里剪切标记元件18,移入剪切工位120’。标记结构100和100’可选择地完全相同,或者它们可以如此地不同,即,标记元件18和标记元件16具有不同的信号产生特征。
通过上述任何过程的改变形成的产品(包括施加至其低粘性的粘合剂表面118的标记元件16和18的传送带116),是一个EAS标记转移片130。转移片130可用于转移标记元件至任何其它的粘合剂表面。例如,转移片130可以用于将标记元件转移至支承片的高粘性粘合剂表面,诸如圆形的支承片12,如图1和2所示。本发明的EAS标记转移片130还对将标记元件转移至其它物体、产品标签或者包装的粘合剂表面有用。对于这些其它的应用。可以使用与这里所示的特殊的标记实施例不同的标记结构和/或尺寸,因为它们可能不需要小型光盘的机械平衡。
在另一个实施例中,在传送带116的标记侧上增添了一个粘附层24,在支承片12如图4B中所示那样是可分离的情况下,转移片130的传送带116可以作为图1、5A-B或者6A-B中所示的任何一种标记的支承片12。
在上述图7-10的过程的一种改变中,上述任一标记实施例的标记元件可以直接地附于支承片12上,而不必附于临时转移片116。
在本发明的另一种EAS标记转移片实施例中(图中未示),在结构100进入剪切工位120前,把高粘性粘合剂层和可去除传送片被叠层或者施加至EAS标记结构100的那侧,该侧与将被附于传送带116的表面118的那侧相对。类似地,在其进入剪切工位120’前,如果使用两个剪切工位,把高粘性的粘合剂层和可去除的传送片叠层或者施加至EAS标记结构100’的那侧。在把可去除的传送层从每一个标记元件去掉后,得到的转移片130适合于将本发明的双态电子物品监视(EAS)标记直接施加于小型光盘的标签表面,或者其它物品。为了将标记元件施加除了小型光盘之外的其它物品,可能需要或者更喜欢不同的结构和/或尺寸。
虽然这里为了解释例示的实施例而示出和描述了特殊的实施例,但本领域的一般技术人员应该知道,设计用于达到相同目的各种改变和/等效的实施可以替代所示出和描述的特殊的实施例,而不背离本发明的范围。一般的技术人员将容易理解,本发明可以用这种实施例来实施。本申请打算覆盖这里讨论的较佳实施例的任何改变和变化。因此,本发明打算由权利要求书及其等效物所限制。
