摘要： A data device for introducing the data read from a recording medium includes first creation device for receiving a read code signal corresponding to the data stored on a data recording medium to create first two phase signals which repeat inversion with a substantially equal period to each other on the basis of a change in the waveform of the read code; second creation device for receiving the first two phase signals to create second two phase signals with their one phase occupying most of their period having an overlapping portion with each other, the period being twice as long as that of the first two phase signals; and third creation device for receiving the read code signal and said second two phase signals to create a second code signal corresponding to the read code signal which shifts during the one phase period of said second two phase signals. The second two phase signals serve to extend sufficiently the window for introducing the read code to provide stabilized read for the data including jitter due to rotation fluctuation of the recording medium.

摘要： A magnetic disk system which records and reproduces data on a magnetic disk at different data transfer rates depending on a track position on the disk includes a transversal waveform equalizing circuit which implements an optimal waveform shaping for a readout waveform. The waveform equalizing circuit consists of a register, a frequency synthesizer, a PLL, and a transversal circuit. The transversal circuit consists of variable delay circuits, variable gain amplifiers, and an adder. The frequency synthesizer produces a write clock signal having a frequency which corresponds to a value stored in the register which depends on the data transfer rate, and the PLL responds to the write clock signal to produce a control signal by which the delay time of the transversal circuit is controlled. Consequently, the delay characteristic is not affected by disparity of circuit components of the transversal circuit, and the write clock frequency and the delay time of the transversal circuit can be set to intended values by merely changing the value stored in the register in response to a variation of the data transfer rate.

摘要： When data are memorized in a 2-7 RLL code on a disc shaped memorizing medium using a sector format, as an address mark in each sector a 2-7 illegal pattern is used; a 1-byte data "8B" in an NRZ signal is converted into a 2-7 RLL code, and further it is modified into the 2-7 illegal pattern.A disc controller in a disc memory inserts the 1-byte data "8B" into a specified position in an NRZ signal and transmits it to an encoder/decoder. In the encoder, the 1-byte data "8B" in an NRZ signal is detected, and a 2-7 illegal pattern is formed by reversing a specified bit of a 2-7 RLL code formed by converting the 1-byte data "8B", and the illegal pattern is sent to the read/write amplifier.
