An information processing apparatus includes a processor configured to acquire information indicating one or more components constituting a processing unit to be processed in each of steps within a workflow, and to execute first display control. The information is acquired for each step. The first display control involves displaying a processing-unit image in a display region corresponding to a first step within the workflow in a case where at least one of one or more components constituting a processing unit to be processed in the first step is in the first step. The processing-unit image indicates the processing unit to be processed in the first step. The display region is provided within a screen indicating progress of the workflow. The one or more components constituting the processing unit to be processed in the first step are identified based on the information.

Information processing apparatus and non-transitory computer readable medium for displaying workflow of processing unit

An information processing apparatus includes an editing unit that edits properties included in a printing job ticket so as to include at least a property used by an equipment and to save a property not used by the equipment, before the printing job ticket is transmitted to the equipment, in a process included in a printing workflow using the printing job ticket, and a transmission unit that transmits a printing job ticket from which the saved property is excluded, to the equipment, in which the editing unit performs editing for including the saved property in the printing job ticket, on the equipment that uses the saved property.

Information processing apparatus, non-transitory computer readable medium storing information processing program, and information processing method

Embodiments of the present invention help to reduce the occurrence of read hard errors in a hard disk drive (HDD). According to one embodiment, a HDD rewrites data on all data tracks of a block M when the number of write operations to the block consisting of continuous plural data tracks. The HDD further rewrites data on continuous plural data tracks and adjacent to the block. Since the number of write operations is counted every block, a memory area to register the number of write operations can be reduced.

Disk drive device and data rewrite method thereof

Embodiments of the present invention help to detect contact between a head and a magnetic disk more accurately in specifying a heater power value for adjusting a clearance between a head element portion and the disk. According to one embodiment, a hard disk controller/multiprocessing unit (HDC/MPU) measures amplitudes of read signals in a user data field DATA. A hard disk drive (HDD) fills a gap between servo data with single data sector. The HDC/MPU measures the amplitudes of read signals in each data sector at different heater power values. It determines the heater power value at which contact occurs from the measured values.

Device and method for specifying control value for controlling clearance between head and disk, and magnetic disk drive device

Embodiments in accordance with the present invention provide a magnetic disk drive capable of achieving error recovery stably in a simple configuration in the event of thermal asperity (TA) and minimizing the error recovery time required, and a method for controlling the disk drive. According to one embodiment, if TA occurs, a cutoff frequency of a high-pass filter to which a data read signal is input is first increased and a loop gain of a low-order finite impulse response (FIR) filter connected in series to an FIR filter is also increased as high as possible. Next, a Viterbi decoder to which a signal is input from the low-order FIR filter provides feedback to the low-order FIR filter so that an input signal error becomes a minimum. Tap coefficients of the low-order FIR filter are thus optimized.
