摘要:
A data conversion method, wherein a sequence of first r-bit datawords is divided into groups of x bits where x is the least common multiple of r and m, an arbitrary first dataword selected from x/r groups of first datawords is divided into x/m, an m-bit second dataword is formed by appending r/(x/m)-bit data, obtained by dividing the first dataword into x/m, to the LSB or MSB side of one or other of the non-divided first datawords, and the word-converted m-bit second dataword is converted to an n-bit codeword (m
摘要:
The method and apparatus records/reproduces multiple kinds of digital signals having different data amounts per unit time on a recording medium. The multiple kinds of digital signals are organized into a plurality of blocks. At least two of the multiple kinds of digital signals are organized into blocks having different lengths. A synchronizing signal is appended to each of the plurality of blocks. The synchronizing signal identifies a length of each of the plurality of blocks. This method an apparatus increase the recording rate, and is therefore suitable for higher density recording. In reproduction, synchronization protection is performed for variable synchronization periods based on the length of the blocks being reproduced.

A data conversion method from m bits of data words into n bits of code words in recording or transmission, in which n is larger than m. A number of bit "0" arranged between one bit "1" and a next bit "1" is restricted to at most 4 in a code string of each code word, and a pair of groups of the n bits of code words corresponding to CDSs (code word digital sum) of two codes +1 and -1 are allowed to correspond to the m bits of data words. One of the two codes +1 and -1 is selectively used according to a DSV (digital sum variation) control signal to convert the m bits of data word into the n bits of code word. A pilot signal formation method using the data conversion method for obtaining a tracking error signal in a magnetic recording and reproducing apparatus, and a rotary magnetic head device for use in a magnetic recording and reproducing apparatus are also disclosed.

摘要:
There is provided a light emitting device which makes it possible to reduce optical loss and improve brightness by increasing a ratio of fluorescent light that is not reabsorbed by a light emitting element while decreasing a ratio of scattered light that is reabsorbed by the light emitting element. Individual faces forming outer faces of the light emitting element 2 are in contact with a bonding member 3 or sealing member 4. The bonding member 3 and the sealing member 4 contain a fluorophor. Emitted light emitted from the faces of the light emitting element 2 is transformed into fluorescent light by the fluorophor. Therefore, the ratio of scattered light that is not transformed from the emitted light into the fluorescent light can be decreased while the ratio of fluorescent light is increased.
