  • Patent number: 7801051
    Abstract: Erroneous detection of a failure in spite of the absence of failure on the route on account of a communication delay is to be prevented. A node device detects a failure on the route to a remote node device is detected by a failure to receive a packet from the remote node device after the elapse of a determined detection time. The node device sets “remote system transmission interval×detection multiplier” to be a first detecting time on the basis of a packet transmission interval determined by negotiation with the remote node device. It also sets the sum of “remote system actual transmission interval ×detection multiplier” and “tolerable delay time” to be a second detecting time. The first detecting time and the second detecting time are compared, and what is longer is determined as the detecting time to be applied to actual operation.

  • Patent number: 7684138
    Abstract: Embodiments in accordance with the present invention relate to detecting a micro-relief that exists on surfaces of a magnetic disk. A phase or frequency of a read signal obtained when data written to a minute projection or a minute concavity on a recording surface of a magnetic disk is read out, differs from that of a read signal obtained when data written to a flat recording surface is read out. The phase progresses in the minute projection, whereas the phase is delayed in the minute concavity. A micro-relief is detected by measuring a deviation value of this frequency, and then defect registration is performed. Embodiments in accordance with the present invention are configured to detect a minute projection whose level does not cause TA. Embodiments in accordance with the present invention may also be configured to provide a highly reliable magnetic disk drive by controlling the flying height in response to a state of a minute projection and that of a minute concavity.

  • Patent number: 7586707
    Abstract: Embodiments of the invention provide a magnetic disk drive capable of reducing an area used for a preamble of each data sector to increase the storage capacity. The magnetic disk drive adopts a data-surface servo system. In one embodiment, main preambles are written on a magnetic disk at a frequency of a data clock. Each of data sectors is written with a write clock that is synchronized with a signal obtained by reading the main preamble. The data sectors include sub preambles respectively. When the data sector which has been written in this manner is read, a read clock is synchronized by use of a signal obtained by reading the main preamble, and a signal obtained by reading the sub preamble included in a data sector to be read. The bit length of the sub preamble is shorter than that of the conventional preamble that is used to independently achieve the synchronization.

  • Patent number: 7570446
    Abstract: Embodiments of the invention provide a magnetic disk drive and its control method capable of effectively using the unrecordable area which is caused due to the composite magnetic head's gap between the read head and the write head. In one embodiment, a disk drive comprises a composite magnetic head structured in such a manner that during write the write head WH reaches each servo area earlier than the read head RH, and a read write control unit to control the write and read done by the composite magnetic head. On the disk, common servo data SP to be used both during read and during write, write servo data SW to be used during write and read servo data SR to be used during read are recorded in this order in each servo area. During write, the read write control unit starts the write head recording data at the timing when reading write servo data SW from the servo area is completed.

  • Publication number: 20090049180
    Abstract: Even when all of usable sessions are in use, a communication can be established for a new session and the interrupted session is automatically restored. Information on degrees of importance of communication sessions and information of restoration requirement are set in advance and stored in a session importance table in association with identifier (URI) of communication initiating terminals and identifier of destinations of communication. When a connection request for a session having a high degree of importance such as an emergency session is received, the session having the lowest degree of importance is selected and interrupted. Information of the interrupted session such as the communication initiator identifier and the communication destination identifier is stored in a session restoration table.

  • Publication number: 20080253295
    Abstract: A failure detection protocol is applied so that failure detection requests for the same aggregated link can be processed even when the failure detection requests differ among routing protocols. The failure detection protocol is executed for each of the physical links that form an aggregated link, and a notification is sent to a higher-level application (for example, a routing protocol), which is a requesting source of a communication line failure monitoring request, with a discrimination between a case in which the communication of the aggregated link in its entirety fails and a case in which some physical links of the aggregated link fail.
