Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing recording apparatuses face challenges in synchronizing clock pulses with data transfer during high-speed data reading and writing operations, leading to delays and reduced performance during continuous shooting or recording, as tuning processes interrupt data writing and reading.
Innovation Solution
A recording apparatus and method that reduce the frequency of tuning by using a generating unit to create a timing signal by delaying the clock signal, a detecting unit to identify errors, and a control unit to adjust the delay amount, allowing for continuous data writing and reading without interrupting the recording process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tuning is carried out to adjust latch timing for high-speed data reading and writing, then data transfer reliability is improved, but recording speed and continuous shooting performance deteriorate due to interruptions
Solution Approach 1:
The system performs tuning in advance before high-speed continuous recording operations begin. By completing the latch timing adjustment beforehand, the timing parameters are optimized for the specific storage device, and then subsequent recording operations can proceed continuously without interruption, thus maintaining both reliability and productivity
Solution Approach 2:
The system implements periodic tuning checks during recording operations. Instead of continuous tuning that would interrupt recording, the system periodically verifies timing accuracy and performs adjustments only when necessary, allowing continuous recording to proceed while maintaining data transfer reliability through occasional timing corrections
2Device complexity
If fixed delay values are used for data latching, then system complexity is reduced, but adaptability to different storage devices and high-speed operations deteriorates
Solution Approach 1:
The system dynamically changes the delay parameter based on the specific storage device being used. Through the tuning process, the optimal delay value is determined for each device and stored, allowing the system to adapt to different storage devices without increasing operational complexity. The delay parameter is adjusted according to device characteristics while maintaining a simple fixed-value approach during actual recording operations
Data Source
AI summary
There is provided a recording apparatus. An output unit outputs a clock signal to a storage device. A communication unit outputs, to the storage device, a write command and data to be written in accordance with the clock signal in order to write the data into the storage device, and receives data for a response to the write command from the storage device in accordance with a timing signal. A generating unit generates the timing signal by delaying the clock signal. A detecting unit detects an error regarding the data received by the communication unit. A control unit carries out an adjustment process on a delay amount in the timing signal in response to the detecting unit detecting an error.
