摘要： An optical device includes a first and second lens group, an operation member, a first and second lens group position detection unit, a storage unit, a control unit. The control unit controls the movement of the second lens group based on positional information of the first lens group detected by the first lens group position detection unit and the positional relationship information stored in the storage unit, and determines whether a control state of the second lens group is abnormal based on control positional information during the control of the movement of the second lens group and the signal corresponding to the position of the second lens group detected by the second lens group position detection unit.

摘要： In an access network using optical switches, communications between an OLT and ONUs are established without a photoelectric conversion performed at an optical switching unit.The OLT controls the downlink optical switch SW(DOWN) to sequentially select each ONU in slots arranged in a discrete manner, and transmits a Discovery Gate message. Upon receipt of the Discovery Gate message, each ONU consecutively transmits Register Request messages. The uplink optical switch SW(UP) sequentially switch signals from ONU#1 through ONU#128 in the slots arranged in a discrete manner, and outputs the signals to the OLT, Some of the Register Requests transmitted from the respective ONUs pass through the SW(UP), and reach the OLT. Based on the received Register Requests, the OLT determines the timing of transmission for the ONUS, and notifies the ONUS of the timing of transmission through a Gate message.

摘要： When a host system has requested the reading of sequential data, a CPU incorporated in an HDD determines whether the data is fragmented into a plurality of data blocks on a disk. If the sequential data is fragmented, the CPU executes the control of reading the data from the disk and transferring it to the host system. In parallel with this control, the CPU also executes the control of writing the data read from the disk, to a contiguous area on the disk.

摘要： A CPU computes a maximum allowable time period for restoration of a sector in which an error occurs, on the basis of a command processing time period designated by a host, when the error occurs upon access to the disk designated by a command supplied from the host, the command processing time period enabling realtime processing. The CPU also determines the use of the computed maximum allowable time period as a maximum error retry time period. The CPU controls the retry of the sector within the determined maximum error retry time period.

摘要： Disclosed is a method of access control for a disk drive whereby an access operation for, particularly, sequentially and alternately executing accesses is supported. A CPU of the present disk drive sequentially and alternately executes accesses to a plurality of data tracks on a disk in response to an access request generated from a host system. During the access operation, the CPU secures time for a look-ahead operation, the time corresponding to the difference between transfer rates. Thus, sequential and alternate access operation in which the number of seek operations can be reduced can be realized.

摘要： Disclosed herein is a system for controlling the process of performing a command in an HDD. The HDD comprises a register for holding the command control information supplied from a host system, a command register for holding a specific command. The HDD further comprises a CPU. The CPU fetches the command control information from the register when the specific command held in the command register is one for setting the command control information. The CPU controls the process of performing a command in accordance with the command control information, thereby to finish performing the command within a period between the time when the host system issued the command and the time when the host system issues the next command.
