Description

光学记录介质及其记录/再现方法
本申请是申请日为2001年11月20日、申请号为01130317.4、题为“光学记录介质及其记录/再现方法”的专利申请的分案中请。
技术领域
本发明涉及一种光学记录介质及其记录/再现方法,特别涉及一种具有在用户数据区域和导出区域的凹槽的至少一个侧面上形成的摆动,并且配置为用户数据区域和导出区域的摆动特征相互不同的光学记录介质及其记录/再现方法。
背景技术
通常,光学记录介质广泛地用作以非接触类型记录/再现信息的光拾取设备的信息记录介质,并且根据信息记录容量分类为CD(compact discs,高密盘)和DVD(digital versatile discs,数字多用途盘)。而且,能够写入、擦除和读信息的DVD盘可以再划分为数字多用途随机访问存储器盘(DVD-RAM)和数字多用途可重写盘(DVD-RW)。
在这种DVD-RAW或DVD-RW盘中,如图1所示,存在导入区域10,其中记录只读数据,如盘大小、一个可读平面上的轨道层数或非法拷贝防止信息,用户数据区域20,其中用户数据可以进行重复读取和/或写入,和导出区域30,其中记录其他与盘相关的信息。
如图1的部分″C″所示,有在用户数据区域20中交替形成的凹槽23和平台25,使得沿着预定的轨道执行记录和/或再现信息标记27。图1中,参考数40表示再现光束。从导入区域10(″A″)和导出区域30(″B″)的放大部分,可以确认物理凹坑15(只读数据)在其上形成。在此,导出区域30执行各种功能。例如,导出区域30保护光拾取器,从而在光拾取器执行记录/再现时不偏离用户数据区域。特别,如图2所示,在具有相反轨道路径的第一记录层L0和第二记录层L1的双层光学记录介质中,导出区域30在从第一层L0最外部圆周到第二层L1最外部圆周的层间跳转的期间保持执行跟踪,而不偏离轨道路径。从第一记录层L0的内部圆周到其外部圆周,然后从第二记录层L1的外部圆周到其内部圆周顺序寻址相反轨道。
在双层只读存储器(ROM)盘中,用作导出区域的区域根据第二层的再现方法进行变化。在具有相反轨道路径的双层ROM盘的情况下,在每个第一和第二记录层的外部圆周分别提供中间区域。在可重写光学记录介质是单层盘的情况下,凹坑和凹槽都可以进行使用。然而,在双层记录介质的情况下,在记录数据期间记录功率受第一记录层L0的物理几何形状影响。换句话说,当在第二记录层L1上执行记录时,记录光束穿过第一记录层L0,导致凹坑部分和凹槽部分之间透光度(transmittance)的不同。
如图3A到3D所示,在镜面(mirror)区域、凹槽区域、凹坑区域和带标记的凹槽区域测量光功率,以模拟依赖于第一记录层L0不同条件下的透光度不同的光功率。在此,考虑由通过棱镜传送的激光束捕获的轨道数。
表1列出用于试验的输入参数和项。表1中,Rc表示记录层的结晶部分的反射率,并且Ra表示记录层的非结晶部分的反射率。

图4是示出根据在图3A、3B、3C和3D中所示的情况下的透光度,光功率的测量结果的图。根据模拟结果,镜面部分中光功率减少最小,并且光功率以凹坑部分、凹槽部分和凹槽标记部分的次序逐渐减少。在双层盘的情况下,透光度根据数据记录期间影响记录功率的第一记录层L0物理几何形状进行变化。因此,有必要统一双层盘的第一记录层L0的物理几何形状,并且因此重新定义导出区域或中间区域。
发明内容
为了解决上述问题,本发明的一个目的是提供一种导出区域配置为在记录和/或再现数据期间防止拾取器偏离用户数据区域而不影响记录功率的光学记录介质及其记录/再现方法。
因此,为达到上述目的,本发明提供一种具有用户数据区域和导出区域的光学记录介质,其中用户数据区域和导出区域均有在其上形成的凹槽和平台,并且在每个凹槽的至少一个侧面上形成摆动,并且导出区域的摆动与用户数据区域的具有不同的特性。
最好,导出区域的摆动通过对用户数据区域摆动的频率、周期、振幅和相位的至少一个特征调制而形成。
另外,导出区域的摆动可以包括形式为锁相环(phase locked loop,PLL)的寻址信息或基准时间信息。
从用户数据区域和导出区域的凹槽读取的信号同步模式最好不同。
预定记录模式最好记录在光学记录介质的最外部圆周,以在记录和/或再现数据期间防止光拾取器偏离用户数据区域。
另外,可以为多层记录提供两个或更多记录层。
两个或更多记录层最好在它们的导出区域中具有不同的记录模式。
导出区域最好具有两倍或更多倍盘偏心度最大允许度的宽度。
在本发明的另一方面,提供了一种多层光学记录介质上的记录/再现方法,包括下列步骤:在所述多层光学记录介质的每个记录层上提供用户数据区域;在所述用户数据区域上形成凹槽;在一个记录层的每个凹槽的至少一个侧面上形成用户数据摆动;以及在所述一个记录层的预定半径之外的区域中形成不同于所述一个记录层的用户数据摆动的导出摆动。
作为替换,本发明提供一种具有用户数据区域和导出区域的光学记录介质,其中用户数据区域和导出区域均有在其上形成的凹槽和平台,在导出区域和用户数据区域中使用不同类型的同步模式。
附图说明
通过参照附图对本发明的优选实施例进行详细描述,本发明的上述目的和优点将会变得更加清楚,其中:
图1示出说明传统光学记录介质的部分A、B和C的放大图;
图2是说明传统光学记录介质的截面图;
图3A到3D说明传统光学记录介质的不同部分;
图4说明不同情况下光功率的试验结果;和
图5是说明本发明光学记录介质的部分A、B和C的放大图。
具体实施方式
参照图5,本发明的光学记录介质包括导入区域100、用户数据区域120和导出区域130,每个区域具有在其上形成的凹槽123和平台125。摆动105和135在每个凹槽123和平台125的至少一个侧面上形成。在此,用户数据区域120的部分″E″和导出区域130的部分″D″在图5中进行放大和显示。参考数110表示激光束。
如上所述,导出区域130防止在记录和/或再现数据期间光拾取器(没有显示)偏离用户数据区域,并且用作保护,以在从双层盘最外部圆周的层间跳转期间能保持执行跟踪。
在本发明第一实施例的光学记录介质中,为了执行保护功能,不同于用户数据区域120中的摆动105的摆动在光学记录介质的预定半径之外的区域形成。换句话说,摆动105和135的周期、频率、振幅和相位这些特征中至少有一种在用户数据区域120和导出区域130中被调制。在调制摆动105和135频率的情况下,导出区域130的摆动135可以形成为具有n倍(n为实数)用户数据区域120的摆动105的基频的频率。例如,为了用作保护,导出区域130可以配置为摆动135具有2倍用户数据区域120的频率。
在调制摆动周期T的情况下,例如,用户数据区域120的摆动105和导出区域130的摆动135分别具有周期200T和100T,从而可以进行区分导出区域130。在完成盘的制造之后,00h作为要写入的模式数据可以记录在导出区域130中。因此,记录/再现期间00h模式数据由信道1(Ch1)进行读出,并且摆动频率或周期由信道2(Ch2)进行读出,从而允许导出区域130的双重区分。
在本发明第二实施例的光学记录介质中,当形成光学介质时,预定记录模式可以记录在导出区域130中,从而鉴别导出区域130。
预定记录模式可以是,例如,在用户数据区域120中使用的记录模式。也就是说,在用户数据区域120中使用的记录模式中,预定记录模式,例如00h模式,重复记录在导出区域130中,从而识别导出区域130。
作为替换,没有在用户数据区域120中使用的记录模式记录在导出区域130中,从而鉴别导出区域130。例如,00h模式记录在用户数据区域120中,而FFh模式作为要写入的另一模式记录在导出区域130中。在此,00h和FFh模式为基于16进制系统的记录模式。
根据本发明的第三实施例,光学介质包括用户数据区域120和导出区域130,每个区域均具有凹槽123和平台125。不同类型的同步模式在用户数据区域120和导出区域130中使用。因此,通过识别同步模式辨认导出区域130,从而在记录/再现期间防止光拾取器偏离用户数据区域120。
在此,导出区域130的宽度可以在大于或等于两倍或更多倍盘偏心度最大允许度的范围内,最好为100μm。
作为替换,本发明提供一种具有两个或更多记录层的多层光学记录介质。多层光学介质包括用户数据区域120和导出区域130,每个区域均具有凹槽123和平台125。摆动105和135在每个凹槽123和平台125的至少一个侧面上形成。摆动105和135可以包括寻址信息或基准时间信息,例如锁相环(PLL)。为了防止光拾取器偏离用户数据区域120,在用户数据区域120和导出区域130中形成的摆动105和135,分别可以调制为不同类型的摆动。在具有两个或更多记录层的多层光学记录介质中,可以在各个记录层的每个导出区域上形成不同的记录模式,从而区分各个记录层。例如,在双层记录介质的情况下,00h模式可以记录在第一记录层的导出区域上,并且FFh模式可以记录在第二记录层的导出区域上。通过如此操作,在/从光学记录介质记录和/或再现期间,记录模式由信道1(Ch1)读出,并且基于摆动调制的摆动信号由信道2(Ch2)读出。因此,可以防止光拾取器偏离用户数据区域120,并且可以区分各个记录层。
为了在层间跳转期间保持跟踪,导出区域130的宽度可以确定为两倍或更多倍盘偏心度最大允许度。如果在生产盘的过程中注入的盘偏心度大约为50μm,导出区域130的宽度确定为100μm或更大。
根据本发明的另一实施例,为了在具有两个或更多记录层的多层光学记录介质中鉴别各个记录层,可以在导出区域130中为每个记录层使用不同同步模式,从而在第一记录层的相同条件下以统一等级保持透光度。
在本发明的光学记录介质中,可以在凹槽123,或凹槽123和平台125上执行记录。
如上所述,根据本发明,在用户数据区域和导出区域上形成凹槽,并且在用户数据区域或导出区域的凹槽上形成不同类型的摆动,从而防止执行再现的光拾取器偏离用户数据区域。另外,在多层光学记录介质中,第一记录层的全部区域配置为具有相同条件,从而防止由于第一记录层透光度的不同而造成的再现和/或记录恶化。
