Abstract: PROBLEM TO BE SOLVED: To achieve an intuitive interface in an information processor to which electronic apparatus is connected.
SOLUTION: A fingerprint sensor 11 is installed on the surface of the casing of a USB memory 1. It is necessary for a user to make the USB memory 1 collate the fingerprint in using the USB memory 1 as a storage medium outside a personal computer. When the USB memory 1 is inserted, an icon showing a drive in such a state that a removable disk is not inserted is displayed in the personal computer. When authentication performed by the USB memory 1 succeeds, information relating to a file stored in an internal flash memory is reported from the USB memory 1 to the personal computer, and the icon showing the file is displayed in the personal computer. The invention may be applied to the USB memory having the authenticating function of the user.

Abstract: PROBLEM TO BE SOLVED: To correct the phase deviation of a reproducing clock signal in a data area on demand. SOLUTION: The clock signal CKL synchronized with clock pits of a disk 11 is generated in a PLL(phase-locked loop) circuit 52 and plural clock signals CK1-CKm are obtained by successively delaying the clock signal CKL every fixed time in a phase delaying circuit 53. After the reproduced signal SMO of the data area of the disk 11 is subjected o the waveform equalizing processing of a PR(partial response), it is converted into a digital signal by using a reproducing clock signal WCK in an A/D converter 42. Signal sampled values yn being output data of the coverter 42 are supplied to a phase deviation detecting circuit 55 and the phase deviation value Δτn from the optimum reproducing clock signal of the clock signal WCK is detected from the signal sampled values and ternary data decision values. Then, the reproducing clock signal WCK synchronized with the reproduced signal SMO by controlling the tacking out of a clock signal in a clock selection circuit 54 so that the phase deviation value Δτn becomes zero.
