TH42087B - How to write sequential audio visual data to disk drive? - Google Patents

Abstract

DC60 (16/09/46) The method for writing the audio visual stream to the disk drive is done by organizing the Organize the data into clusters and start writing these clusters down to the physical sectors it finds as The first sector after which the read / write header has resigned to the desired track on a disk that is spinning a cluster. It contains a number of blocks of information equal to the number of sectors on the track that. There is an integer number on the disk, so writing a single cluster is Writes to full tracks with an integer number on disk. Although the disk drive may have an index. Physical to identify physical sectors at all one track. But it will be able to write information of Can be clustered without considering the position of the index During the interleaving of audio visual data, when multiple recording tasks are executed in cycles, until all missions are completed, a cluster is written in part one of the first task. During the cycle or period Insert one toggle and then position the header with the other track where the Write the cluster in part one of the second task during the next interrupt period starting from The physical sector that the header encounters is the first, so there is no need to wait for the index either.The location where the first block of data in the cluster has been written down is indicated by writing the block number. In the physical sector or by writing the beginning of the cluster indicator on the track being written.

Claims (2)

1. How to write data from the host to a disk drive with the disk drive having a header. For writing data and discs that have more than one track of data, where each track of the data is displayed. There will be more than one physical sector. The method includes - getting streams from the server - organizing the stream into more than one cluster of data. Where each cluster has more than one block of data, where the blocks in a cluster are numbered equal to the integer multiplier of the sectors in a track. - Positioning the header to where It starts writing the stream - writing the first block of the first cluster down to the found physical sector. Is the first sector with that header after that header is positioned to match the track and - the subsequent blogging of the first cluster down. To the physical sector The headers are found in the following sequence. 2. Method of claim 1, which has an additional step, is to assign a position to the header. It coincides with the second track after the first cluster is written, writing the first block of the second cluster down to the underlying physical sector where the header is found after that header is positioned. So it is already in sync with the second track and the subsequent block of the second cluster is down to the sector. The physical form that follows the headers found 3. Method according to claim 2, which has an additional step is to store positional information. Of the physical sector for one or more blocks. 4. The method according to claim 3, where the positional message collection consists of Write down the number of blocks in at least one of the aforementioned physical sectors. 5. Method according to claim 3, where the positional message storage consists of: Writing the beginning of the cluster identifier on the track on which the cluster is written 6. Method according to claim 1, where at least one block of data in each of the cluster identifiers is written. The cluster will contain an error code message. And where the data flow is organized into a cluster of more than one cluster of data includes data computation, error correction for Each cluster from a group of blocks of data in each cluster. 7. Procedure according to claim 6, where the message shows a solution to the error. The calculation consists of information showing the conditions of even or odd in the calculation. The computation consists of Reed-Solomon Correction Code Calculation 9. Clause 1 Method, where the integer multiplier is equal to 1, where all data blocks in the first cluster are written. To the physical sector within the same track 1 0. Method for claim 1, where such integer multiplier is at least 2 and where the next block is written down. To the subsequent physical sectors consisting of Writing to fill the physical sector on track one and then position the headers straight. With adjacent tracks and write them down to the physical sectors in the adjacent track until every block is completed. In the first cluster 1 1. Method according to claim 1, where the server is an audio visual system and where The stream is Audio Visual 1. 2. Method according to claim 11, where the audio visual stream is the data stream.
