摘要:
Detection capability of a servo timing mark (STM) is improved. Long STM is configured by pseudo-STM forming part of an AGC/PLL pattern and intrinsic STM. When a system can not recognize the intrinsic STM, it keeps a state that a sector detection window is opened, and is operated in a long STM detection mode to recognize the long STM, thereby generates an STM detection signal. After the STM detection signal has been generated, an STM detection window is closed, and the system is operated in an intrinsic STM detection mode. Since the long STM has longer bit length than the intrinsic STM, it has high discriminating power with respect to other bit patterns. Therefore, even if the sector detection window is remained to be in an opened state, bit strings of data sector, address information in a servo sector or the like is not falsely recognized.

Embodiments of the invention allow a heater to reduce the clearance between a head element section and the magnetic section while reducing the risk of collision between the head element section and the magnetic disk during load/unload. In one embodiment, an HDD judges whether a heater is ON or OFF after the load process is started. If the heater is found set to ON, the HDD sets the heater to OFF. With the heater kept OFF, the HDD starts the actuator pivoting. If the heater is found set to OFF, the HDD moves the actuator from the parking position to the magnetic disk with the heater kept OFF. Upon completion of the load process, the HDD goes to the subsequent process. Since the heater is OFF during load, the risk of collision between the head element section and the magnetic disk is reduced.

A disk drive and a control method for the disk drive to reduce the number of unnecessary write inhibition operations. A microprocessor unit (MPU) 6 sets an allowable value Cv for the velocity of a magnetic head 1 to V0 until the head passes over N1 sectors after completion of a seek operation, Cv to V1 until the head passes over N2 sectors after passage of N1 sectors, and Cv to V2 after passage of N2 sectors.

Image data obtained by photographing an object using a camera is stored in a storage medium that can be attached to and detached from the camera. The camera includes a device program storage unit and an information writing unit. A device program that can be executed by an information processing device, which is different to the camera, is stored in the device program storage unit. The information writing unit is constituted to be capable of writing the device program to the storage medium attached to the camera. While writing the device program to the storage medium, the information writing unit writes the device program in a format enabling the information processing device to read and execute the device program automatically when the storage medium is attached to the information processing device.

Embodiments of the invention prevent data loss due to very frequent writing onto adjacent data tracks. In one embodiment, an alternate zone made up of multiple adjacent data tracks is formed by setting data tracks whose usage is to be prohibited for every other data track. The data updated very frequently and data not updated too frequently are recorded in the alternate zone. Data tracks for recording the data updated very frequently, and data tracks for recording data not updated too frequently, each have one cylinder of spacing. Data loss due to leakage fluxes can thus be prevented.

摘要:
A control apparatus is connected to at least one terminal device to control the terminal device. The apparatus includes a communication unit which communicates with the terminal device, a display unit which displays an operation window, an information acquisition unit which acquires, from the terminal device through the communication unit, information concerning operation of the terminal device and operation object for operation, an arranging unit which arranges the operation object to produce an operation window and is stored in the control apparatus, and a command generating unit which generates a control command in accordance with operation on an operation window, wherein when the operation object is operated, the command generating unit generates information which specifies the operation object which has been operated and a control command including information concerning an operation amount, and the communication unit transmits the control command to the terminal device.
