TH34395B - Recording device - Google Patents

Abstract

The DC60 (04/10/54) provides a recording device including a recording medium with a data area whose address number is assigned to each. Groups with predefined sizes Interface for attaching to the host device. Write path for writing data in the data area. The way to decide the access rank for the data fragmentation of Such a log medium is divided into a number of regions, each of which has an alternative data capacity, and decides the space access rank divided by the written path. Timing Decision Method for Decision Making The time when file information on written data is updated. control method for control The written path to access a certain number of partitions corresponds to the decided access rank. Find an empty group in access area and write the data in the empty group that is searched and how to update file information for Updating file information on the already written data. Provide a recording device, including a recording medium, with a numbered data area assigned to each. Groups with predefined sizes Interface for attaching to the host device. Write path for writing data in the data area. The way to decide the access rank for the data fragmentation of Such a log medium is divided into a number of regions, each of which has an alternative data capacity, and decides the space access rank divided by the written path. Timing Decision Method for Decision Making The time when file information on written data is updated. control method for control The written path to access a certain number of partitions corresponds to the decided access rank. Find an empty group in access area and write the data in the empty group that is searched and how to update file information for Updating file information on the already written data.

Claims (5)

1. A recording device, which consists of: a recording medium containing a data area with a number of addresses assigned to each group with a predefined size, interface unit for connection to the host device. The write path is for writing data that is output from the host device through a interface. Harmonize them in the data area of the said medium. The access ranking decision path for dividing the data area of such record medium into A number of areas, each with an alternative data storage capacity. And when the data is written Will decide the rank Access to a number of the aforementioned divide areas from the aforementioned writing methods. Decision pathway; timing for decision making; timing when file information on data. That is written will be updated. Corresponds to the decided access rank By way of decision Rank of such access Control Path for controlling such writing paths when data is output from the host device. Through the interface it is written in the data area of the said medium. To reach the area Divide a certain number according to the access rank decided by the decision path. To search for an empty group in an accessible area. And to write information in the search empty group and the means of updating to the file information for updating to the The file information on the written information is consistent with the timing decided by the decision path. The timing of the said 2. Recording device according to claim 1, where: the recording medium contains the file information area on which the file information will be written and the means of updating it to the file information. Already written to the information area of the file At scheduling that is decided by the decision-making method Such timing 3. The recording device according to claim 2, where: when the area of the region divides the number on which the area data is written corresponds to the access rank at Decide by Decision Path, the access rank becomes adjacent to or close to the said file information area, such scheduling decision path decides the timing in the form of information. The file on the written data is updated after the data is written in the area. Close to or near the file information area 4. A recording device according to claim 1, which is also included: a non-volatile storage medium containing a data area consisting of a number of areas, each containing Preset size where: The way to update the file information will write the file information of the data that Written successfully in the optional area of the storage medium, it does not vanish at the scheduling that decides. By the method of determining the time 5. Recording device, which includes: a recording medium with a data area with a number of addresses assigned to each group with a predefined size, an interface for connecting to the host device. The write unit for writing the networked data from the host device through its interface. It in the data area of the said medium. The access rating decision unit for dividing the data area of such record medium is A number of areas, each with an alternative data storage capacity. And when the data is written Will decide the rank Access a number of divider areas from the said unit. Judging unit in timing decisions for scheduling decisions when file information on data. That was written to be updated Corresponds to the access rank that is decided by the ranking decision unit. Such access A controller for controlling such a write unit when data is output from the host device through The interface is written in the data area of the log medium. To reach the dividing area Some correspond to the access rank decided by the access rating decision-making unit. To search for an empty group in an accessible area. And to write information in the search empty group and the update unit to the file information for the update to The file information on the written data is already consistent with the scheduling decided by the decision-making unit. Arrange the timing at that time
