However, as was mentioned previously, the data in each of these frames is widely distributed along the disc's spiral data track. Nec i-Select D3210 Audio fact, data stored on the disc data track is organized as contiguous byte blocks called "eight-to-fourteen modulation EFM frames.

Each byte of user data in a given EFM-frame is obtained from twenty-four different byte data frames that are distributed over contiguous data frames. Thus, the 24 bytes of a given data frame are distributed over consecutively recorded EFM-frames on the disc. But, in order to recover the 24 bytes of a single data frame from the disc, consecutive EFM-frames have to be retrieved the additional 5 EFM-frames contain all the ECC parity data needed to complete, and thereby render decodable, Nec i-Select D3210 Audio ECC codewords that protect the specific byte data frame. Unfortunately, this segmentation cannot be used to precisely define where on a CD-ROM disc the boundaries, or start, of a given sector resides. To facilitate locating information on a CD-ROM disc each sector contains "address" data, which is used by the CD-ROM drive's controller to identify specific sectors the computer operating system also uses a translation of this address data, together with the disc directory and file allocation tables, to identify how the user data in the sectors relates to the files on the disc.

Thus, to retrieve a specific sector from a disc the CD-ROM drive must first read approximately sequential byte EFM-frames from the disc and then deliver the data contained in them to the drive's controller which "finds" the 98 sequential byte data frames that comprise the sector and extracts the desired user data.

This is because entire or complete error correction codewords must be recovered before decoding of the ECC words can be accomplished; the data needed to complete all of the error correction codewords that protect data that resides in the sector of interest is distributed over contiguous EFM-frames. The underlying CD-Audio recording format specifies this wide scattering of the data that comprise Nec i-Select D3210 Audio codewords to enable the correction of long data error bursts that may be caused by large defects on the disc caused by handling. CD-R writers can write entire discs at once, or they can write a portion of a disc called a "session". In addition, the CD-R standards provide for the writing of small segments of data, e.

When appending any new information to a disc i. Moreover, in packet writing, at least four "link sectors" and usually seven to eight sectors, in practice that Nec i-Select D3210 Audio useless padding data must be appended to the sectors of user data that one wants to record. These recording characteristics i.

In particular, the recording formats Nec i-Select D3210 Audio by DASDs cause Nec i-Select D3210 Audio bytes that comprise a specific sector to be contiguously recorded along a continuous segment of the data track on the storage medium and further cause sectors to synchronously occur along the data track so that DASDs know the exact physical location of every sector recorded on their storage medium. Moreover, a DASD storage medium is subdivided into sectors prior to writing file data to it this is done via a process known as "formatting". Thus, a DASD can write, or read, a single sector as an independent unit and it can locate a sector anywhere on its storage medium, regardless of how much of, or what portion of, the medium is already written.

These operational features allow fast file access e. However, the incorporation of CD-writers into personal computers and work stations is Nec i-Select D3210 Audio impeded by the fact that they cannot perform DASD-like operations, i. One attempt at solving this problem is the Power Disc PD optical disc system recently introduced by Panasonic, which can read any compact disc i. It is another object of the present invention to provide a system compatible with prior CD standard formats.

It is also an object of the present invention to utilize the eight-to-fourteen EFM modulation scheme and the channel bit frames utilized in the CD-Audio format in the CD-DASD format that is, the low-level physical manifestation of the CD-Audio format is not altered. It is another object of the present invention to accommodate variance in switching times between modes among different CD-DASD drives. It is an additional object of the present invention to provide a system that improves the access time to recorded data by allowing reading or writing while the disc is changing speed. It is another object of the present invention to provide a means of decoding the RS Nec i-Select D3210 Audio correction codes that will provide high recovered data reliability and enable fast access to certain recorded information fields such as sector ID fields.

The above objects can be accomplished by a system that redefines how logical data is distributed on the compact disc CD. This product code can be interleaved to mitigate the effects of user handling of the disc. This feature will assist data reading and writing while the CD is acquiring proper rotational speed assuming a constant linear velocity system.

These, together with other objects and advantages which will be subsequently apparent, reside in the Nec i-Select D3210 Audio of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout. The present invention defines a recording format that i enables full support of DASD operation and ii which Nec i-Select D3210 Audio realized by redefining how the logical byte EFM-frames i. The invention redefines which physical marks on the disc will represent each of the data in these logical byte EFM-frames. During the formatting operation sector headers are written globally over the entire disc or over an annular portion that is allocated to CD-DASD use.

Alternatively, the sector headers could be embossed or otherwise formed on the disc during its manufacture. The physical marks on the disc that constitute the sector headers are formed using channel data sequences that maintain the 2,10 run-length constraints that characterize Nec i-Select D3210 Audio physical marks of the low level CD recording format.


The present invention is applicable to the typical computer system, as illustrated in FIG. The present invention is involved in the Nec i-Select D3210 Audio of the disc drive This error-correcting code employs two distance 5, Reed-Solomon codes: The conventional encoding and recording process performs the following steps cf. The byte user data frames are scrambled and then 24 bytes comprised of a first group of twelve contiguous bytes and a second group of twelve additional contiguous bytes that occur 48 bytes later in the sequential stream of scrambled data are Nec i-Select D3210 Audio, that is, 4 parity bytes are calculated and provided to each block of 24 scrambled and delayed bytes to form a byte C2 codeword The individual bytes of every C2 codeword are delayed for a variable number of words.


These variable length delay lines provide the "cross-interleave" feature of the encoding. Free Download Nec i-Select D Audio Drivers (Sound Card). Audio Drivers for PowerMate VL5 Flex systems / i-Select D download.
