    摘要: A carriage for a disc device, which has a top arm, bottom arm, and mid arm, has a main mode, end arm mode, and mid arm mode as a frequency response obtained when subjected to a vertical shake. In the main mode, all of the top, bottom, and mid arms swing at a first frequency within the same phase in a primary bending mode. In an end arm mode, the top and bottom arms swing at a second frequency higher than the first frequency within opposite phases and with an amplitude larger than that of the mid arm. In the mid arm mode, the mid arm swings at a third frequency having a difference of 50 Hz or less from the second frequency within the same phase as in the main mode, and the top and bottom arms swing within the phase opposite from that in the main mode.

    摘要: A packet aligning apparatus includes a packet analyzing section configured to receive a reception packet, and extract a sequence number contained in the reception packet; a packet storage section; a write control section configured to determine whether the reception packet is stored in the packet storage section based on the extraction sequence number or transferred to a subsequent block; an expectation managing section configured to generate expectation data which indicates the sequence number of the packet which should be transferred next to the subsequent block, as the expectation; and a read control section configured to read a group of storage packets stored in the packet storage section, to transfer to the subsequent block. The write control section compares the extraction sequence number and the expectation, stores the reception packet in the packet storage section when the extraction sequence number is larger than the expectation.
