摘要： A magnetic-disk substrate has an average value of squares of inclinations that is 0.0025 or less, and a frequency at which squares of inclinations are 0.004 or more is 15% or less, in a case where samples of inclinations on a main surface are obtained at intervals of 10 nm. The main surface is configured to receive at least a magnetic recording layer thereon. The magnetic-disk substrate includes an outer circumferential end portion and an inner circumferential end portion, and the outer circumferential end portion and the inner circumferential end portion have chamfered portions.

摘要： An IC card reader/writer has frequency mode identifying means for determining whether or not an IC card loaded thereon has an identifiable frequency. When the frequency mode of the IC card is identifiable, clock frequency determining means reads frequency data representative of an operating clock frequency out of the IC card to determine an operating clock frequency particular to the card. Based on the determined operating clock frequency of the IC card, frequency setting means converts reference clock pulses being generated by reference clock generating means into clock pulses which match the clock frequency of the IC card, and feeds those clock pulses to the card. The reader/writer is capable of producing clock pulses the frequency of which is variable in matching relation to the frequency of operating clock pulses of an IC card.

摘要： The present invention relates to a secret identification number checking system for comparing a secret identification number stored in a magnetic card (11) and a secret identification number entered by the bearer of the magnetic card. Data to enable the comparison is stored in a card medium (13), and the card medium (13) and a transaction machine (17) mutually authenticate each other. When if both the card medium (13) and the transaction machine (17) are legitimate, the card medium (13) sends the data to the transaction machine (17) to permit the secret identification number stored in the magnetic card (11) to be compared with the secret identification number entered by the bearer of the magnetic card. The secret identification number checking system thus improves the security of transactions.
