Abstract

PURPOSE:To estimate the remainder of a recording medium and to write an appropriate quantity of information by detecting the remainder of the magnetic recording medium from a directory used for an operation system and displaying the difference between that and a written information count value. CONSTITUTION:When the magnetic recording medium 4 is set to a magnetic recorder 3, a recognition device 5 in a remainder display device 2 recognizes the operation system from a CPU 1, and a remainder detection device 6 decides the remainder of the medium 4 based on the presence or absence on a directory medium 4 corresponding to each operation system and displays the remainder on a display device 8. If information is written on a medium 4 in that state, it is counted by a counter 7, and the remainder obtained by subtracting the counted result is displayed on the display device 8. The remainder of the recording medium 4 is estimated, and an appropriate quantity of information is written without data loss caused by writing beyond the limit of capacity.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は磁気記録装置の残量表示装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a remaining amount display device for a magnetic recording device.

〔従来の技術］ 従来、この種の磁気記録装置は、磁気記録媒体を使用中

？表示する表示装置８とを備えている。FIG. 1 is a block diagram of one embodiment of the present invention, with reference numeral 1.
2 is a remaining amount display device, 3 is a magnetic recording device, and 4 is a magnetic recording medium. Also,
The remaining amount display device 2 includes a recognition device 5 that recognizes the operating system, a remaining amount detection device 6 that detects the directory of the magnetic recording medium and the remaining amount of the magnetic recording medium 4, and a counter 7 that measures the flow of information. And the remaining amount of counter 7 output? It is equipped with a display device 8 for displaying images.

続いて本実施例の動作について説明する。Next, the operation of this embodiment will be explained.

置８にこれを表示させる。First, when the magnetic recording medium 4 is set in the magnetic recording device 3, the recognition device 5 recognizes the operating system on the CPU l and detects the directory area, and the remaining amount detection device 6 detects the magnetic recording medium 4. Detect the remaining amount. The remaining amount detection device 6 causes the counter 7 to store the remaining amount, and simultaneously causes the display device 8 to display this.

８にこの値を表示する。Next, when information is written from the CPU to the magnetic recording medium 4, the amount of all information is measured by the counter 7. Here, the counter 7 calculates the difference in the amount of information measured from the remaining amount at the time when the magnetic recording medium 4 is set, and displays it on the display device 7. That is, the counter 7 immediately counts the difference between the remaining amount of the magnetic recording medium 4 at the time of setting and the amount of information written to the magnetic recording medium 4, and displays this value on the display device 8.
