摘要： A propagating method is provided in which timing and servo sector information is propagated throughout a data storage media that initially contains only a guide pattern. The method uses an offset between the write element and the read element in a read/write head to position and propagate the timing information. In addition, a method for circumferentially aligning timing and servo sector information is disclosed that utilizes a time delay to position the propagated timing and servo sector information. Another method for attenuating timing errors during timing and servo sector propagation to a data storage media is disclosed. Timing errors are attenuated through the use of phase locked loop circuit and measurement of the phase error detected between different tracks on the data storage media. Apparatuses implementing the methods including a storage device readable by a computer system that implements the methods are provided.
摘要翻译： 提供传播方法，其中定时和伺服扇区信息在最初仅包含引导图案的数据存储介质中传播。 该方法使用读/写头中的写元件和读元件之间的偏移来定位和传播定时信息。 此外，公开了一种用于周期地对准定时和伺服扇区信息的方法，其利用时间延迟来定位传播的定时和伺服扇区信息。 公开了在定时和伺服扇区传播到数据存储介质期间衰减定时误差的另一种方法。 定时误差通过使用锁相环电路和测量在数据存储介质上的不同轨道之间检测到的相位误差来衰减。 提供实现包括实现该方法的计算机系统可读的存储装置的方法的装置。

摘要： A format for accessing content such as a full-length move from an optical disc uses an XML description file stored on the disc to generate one or more screens that a user employs to access the content. The decoding requirements of a hardware or software player are reduced by discarding specific elements of an encoding standard such as MPEG4 that is used to encode the content on the disc. The maximum average and peak bitrates at which the data is transferred are limited to further reduce the demands on the player.
