摘要： Digital data is formatted and recorded in track pairs on a tape by the rotary heads of a DAT so as to have a header portion for each track which includes a frame number, error correcting code, ID and so on added to the digital data, the content of each header portion of the tracks for any given frame being equal whereby it is possible to easily detect, upon reproduction, unerased data signals due to head clogging and so on by comparing portions of the two header portions of each frame and error correcting the data from those tracks where it is determined that the compared header portions contain different data.

摘要： A method is disclosed for effecting update-in-place of data that has been recorded on tape in oblique tracks using a helical-scan recording technique. The data to be updated is recorded in a block of M tracks lying between first and second continuum each at least of N tracks where N is the worst-case number of tracks required to achieve head/track alignment. The block of M tracks comprises a first series of at least N tracks, a second series of tracks containing the data, and a third series of at least P tracks. When updating the data, the block is rewritten as a whole in a single continuum with the first track of the block being written within a distance of P tracks from the last track of the first continuum.

摘要： In this invention, a predetermined amount of data is given as one frame, and data having a predetermined format is recorded for each frame. A first area recording main data and a second area recording sub data are formed in each frame. Plural types of units each consisting of a plurality of frames are set, and a number of first units from a leading end of a recording medium and the numbers of other units from the leading end of the recording medium to a trailing end of the first units are recorded in the second area of a frame constituting the unit including the trailing end, thus facilitating a high-speed search operation.

摘要： Audio-centered information is stored on a unitary medium by using a Table-of-Contents (TOC) mechanism that specifies an actual configuration of various audio items on the medium. In particular, each one of a set of one or more Track Areas gets at least two mutually logically conforming Sub-TOCs assigned. This allows to retrieve any constituent Sub-TOC part from at least any correct copy of the Sub-TOCs. Furthermore, one or more Master-TOCs are provided for specifically pointing to each of the Sub-TOCs.

摘要翻译： 以音频为中心的信息通过使用指定介质上各种音频项目的实际配置的目录（TOC）机制来存储在单一介质上。 特别地，一组一个或多个轨道区域中的每一个获得分配的至少两个相互符合逻辑的子TOC。 这允许从子TOC的至少任何正确副本检索任何组成子TOC部分。 此外，提供一个或多个主TOC以专门指向每个子TOC。
