Document Type and Number:
Japanese Patent JPH07270946
Kind Code:
A
Abstract:

PURPOSE: To realize a reproducing device, recording method and recording medium capable of markedly lowering an error rate.

CONSTITUTION: The reproducing device 10, recording method and recording medium capable of markedly lowering the error rate are realized by setting the length of the second dots in the arranging directions of the first and second dots larger than the length of the first dots at the time of forming the first dots to allow transmission of light and the second dots to shield the light on the translucent recording medium and recording digital information by combination of the arrangement of the first and second dots and setting the slice level at the time of reproducing the digital information by irradiating the recording medium with light and subjecting the transmitted light to photoelectric conversion by using a photoelectric conversion means 23, at <50[%] when the signal level corresponding to the first dots among the outputs of the photoelectric conversion means 23 is set at 100[%] and the signal level corresponding to the second dots at 0[%].
