    Abstract: In one embodiment, a write/read apparatus includes an external interface section for data input; an external interface section for data output; a memory for temporarily storing the data that is input through the external interface section for data input and written on the recording medium and the data that is read from the recording medium and sent to the outside through the external interface section for data output; an address generating section for generating unique addresses associated with physical block addresses of the recording medium; a flag generating section for generating flags for prohibiting overwriting of the data to be written on the recording medium; and a processing section for adding the unique addresses generated in the address generating section to the data that is stored in the memory and that is to be written on the recording medium. The data with the addition of the flags generated in the flag generating section and the unique addresses is written on the recording medium.

    Abstract: Embodiment of the present invention provide a technique for carrying out work in a short time to prevent without fail data stored in a read/write device from leaking to persons other than an authorized user. There are provided a read/write device, and a format management method for managing a format of data stored in the read/write device. A given change factor is specified for a format of data stored in the read/write device. A format change judgment part for judging whether or not the change factor exists is provided in the read/write device or in a host device connected to the read/write device. Then, a given offset coefficient is generated for a format table according to an instruction from a format change judgment part, and a different format table is generated according to the generated offset coefficient and the format table.

    Abstract: A signal processing delay circuit is fabricated as a semiconductor integration circuit to cope with increase in the data transfer speed and data recording and reproducing density on a recording medium. In the delay circuit, the amount of delay of a reference delay circuit of a delay PLL is controlled to take a fixed value independent of deviation in quality of the semiconductor circuit, change in power, and alteration in temperature. A control signal supervising the delay amount of the reference delay circuit is employed to control amounts of delay of input signals supplied to a window adjustment delay circuit of a window adjustment circuit and a T/2 generation delay circuit generating a synchronizing signal. Each of these delay circuits includes an analog variable delay circuit having the same configuration. The window adjustment delay circuit is supervised by a signal obtained by weighting the control signal by a D/A converter. A data acquisition circuit and a data write circuit each include an analog variable delay circuit.
